What week does semester 3 start? What week does the third trimester of pregnancy start from. How to count during pregnancy

The onset of the third trimester means for a woman that she has reached the “finish line” - childbirth is very soon. This article will help you not to get confused in terms and correctly calculate when this final period begins.

Enter the first day of your last menstrual period

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 30

Timing

Third trimester of pregnancy - these are the seventh, eighth and ninth calendar months of the gestation period. If we consider it as it is customary in obstetric practice, then half of the seventh, eighth, ninth and tenth months fall into the third trimester, since there are exactly 4 weeks in one obstetric month, which cannot be said about the calendar.

There is usually no way to determine the exact moment of conception, and therefore it is customary to count the gestational age from the first day of the last menstruation. Thus, the 3rd trimester of pregnancy begins at 27-28 weeks of gestation, and when it ends, no one knows for sure - this question is purely individual. The beginning of the period is the same for everyone, and how long the trimester lasts depends on when the birth occurs.

In every third pregnant woman, according to statistics, the third trimester successfully ends with childbirth on time at 38 weeks. In the period from 39 to 40 weeks, about 45% of women give birth, the rest either give birth before 38 weeks, or go to the maternity hospital at 41, 42 weeks.

Peculiarities

The onset of the final third of the term for bearing a baby for a woman means that the easy period is over, and now, for understandable physiological reasons, it will be more and more difficult to carry a baby every day. The child has reached a large size, he continues to grow and gain weight, the woman herself has also gained a lot of weight. By 35-36 weeks, the uterus reaches its maximum size - it has nowhere else to grow.

It is the large uterus that causes discomfort in the third trimester. It puts pressure on the diaphragm, which leads to shortness of breath, squeezes the woman’s stomach, which sometimes leads to unbearable heartburn, the compressed intestine cannot fully function, which causes constipation and exacerbation of hemorrhoids. The load on the spine leads to back pain, the load on the legs leads to pain in the lower extremities, and sometimes to varicose veins. The effect of hormones complements the picture of the expectant mother's everyday life - relaxin leads to softening of the bones and ligaments of the pelvis, which causes pain in the coccyx and pubic bone, accumulating oxytocin enhances training contractions, anxiety and fears return, and depression may develop.

The child is fully formed, he is well protected, so at the current time he is almost in no danger. You can already take many medicines that were previously prohibited.

The main danger in the current period lies in the possibility of fetal hypoxia, because from the 34th week the placenta reaches its maximum degree of maturity and begins to age, copes worse with its duties.

There is no need to rush things - the last weeks of pregnancy, although difficult for the mother, are necessary for the baby: in his lungs, the process of accumulation of surfactant, which is necessary to ensure the possibility of independent breathing, is completed, the weight gained by the baby is not only plump cheeks and buttocks that are pleasant to the eye, but also the opportunity effectively regulate your body temperature, keep warm after birth. These two signs are extremely important for a baby at birth. It is in the last weeks, starting from 32-34 weeks, that the baby begins to undergo the most important process of learning adaptability - he will have to change his environment, and his small body activates adaptive abilities in advance.

Difficulties that women may face during this period:

• anemia;
• gestational pyelonephritis;
• fetal hypoxia;
• gestosis.

Compliance with all doctor's recommendations will help to exclude such complications.

Simple recommendations from specialists will help make the third trimester easier.

• Move more, do gymnastics, walk, walk, do housework. Movement is not only life, but also an effective preparation of the cervix for childbirth.
• Change your diet - add more vegetables and fruits, reduce the amount of foods high in calcium, red meat is best replaced with fish or chicken breast.
• If the estimated fetal weight is large, stop taking multivitamins in the third trimester.
• Monitor your well-being. If there are signs of a mucous plug discharge, water leakage, intimate contacts and bathing are prohibited, and if regular contractions appear or water flows out, you need to go to a maternity hospital.
• Diseases such as influenza or chickenpox at this time are dangerous not so much for the baby as for his mother, since they aggravate her already difficult condition. That's why avoid contact with sick people and pay sufficient attention to the prevention of infectious diseases.
• It is important to carefully count the movements every day.. If there are suddenly few of them, or the baby, on the contrary, behaves too actively, you need to consult a doctor - both of them can be signs of hypoxia, that is, oxygen starvation of the baby.
• Practice proper breathing and exercises to relieve labor pain. This can be learned in courses for pregnant women, which operate free of charge in every antenatal clinic.

Do not try to induce labor on your own or to hasten labor at home.

Every woman during the period of bearing a child should be aware of the ongoing changes in the organisms of both. In order to avoid negative consequences, it is important to know which symptoms are the norm for pregnancy, and which should be treated with caution.

What week does the 3rd trimester of pregnancy begin and how long does it last

The waiting time for a child cannot be an unpleasant event, especially if the pregnancy is long-awaited and planned. Every week something new happens to the growing embryo, it develops and gains weight. Every trimester also affects the mother's body.

The last trimester (third) starts from the 7th month of pregnancy or from the 27th week and lasts until delivery. This is the period when a woman has already suffered toxicosis, managed to feel the movements of the fetus and realize all her future responsibility. Next, you will find out what else happens to the child and the expectant mother at this stage.

Beginning of trimester (weeks 27-28)

At week 27, the weight of the fetus is approximately 1 kilogram. At this time, premature birth no longer poses a strong danger; thanks to special devices, a premature baby can exist independently.

Child

In his body, all the organs have managed to fully form, the remaining time, their work will prepare for independent functioning. The baby can perform training movements with the lungs.

By conducting an ultrasound, it is possible to see the facial features of the embryo, some have hair on their heads.

Fetal movements may consist of clenching hands, sucking fingers or toes. The skin is still quite thin and blood vessels are visible through it, but since that time it has already begun to gain fat to maintain the thermal regime in the body. The baby opens his eyes with eyelashes already appearing on them and gives a reaction to a bright light.

Mum

A woman feels discomfort in the uterus, due to its constant increase. It is becoming more and more difficult to find a comfortable position, it is highly not recommended to stay on your back and cross your legs for a long time, since a bulky uterus can compress a vein supplying blood to the heart.

There is heartburn and shortness of breath, frequent urge to urinate, bloating and constipation are not excluded. By the beginning of the 3rd trimester of pregnancy for a woman, the rate of weight gain is 7-8 kg.

It is not uncommon that toxicosis occurs in the later stages. Dizziness and lack of air in the premises is the norm, if not permanent. It is recommended to spend more time walking.

If fetal movements are felt very rarely or do not occur at all, this is a serious reason to consult a doctor, the following symptoms are unnatural for the normal course of pregnancy:

• watery discharge or those that contain blood;
• the occurrence of pulling or sharp pains in the uterus.

What should be the diet of a woman

In a difficult period for the body, weight gain occurs rapidly, which will not positively affect the course of pregnancy. In the diet of a woman in position should be included in the smallest amount, and it is better to completely exclude:

• smoked, fried and spicy food;
• raw eggs (dishes containing them should also be limited);
• seafood without heat treatment;
• poorly fried meat;
• alcohol.

• confectionery and flour products;
• chocolate products;
• potato;

Will benefit the baby and expectant mother:

• vegetables;
• whole grain cereals;
• fruit;
• Brown rice;
• corn;
• coarse bread.

Mid trimester (34th-35th week)

By the 35th week of a woman's pregnancy, the weight of a child is about 2.5 km, and its length is about 50 cm. The respiratory system is completely ready and in case of premature birth, the baby will no longer need devices.

Fetus

The kid in this period has already accumulated subcutaneous fatty retina, clear lines have formed on his face. The heart of the fetus beats in a rapid rhythm, with the help of a special device it is possible to fix more than 120 beats per minute.

The middle of the last trimester strengthens bone tissue, and the nervous system completes the stages of its formation.

The child clearly hears sounds that are unpleasant for his hearing and can be commented on by sharp shocks. The formation of the genital organs of the boy is almost complete. The appearance of the fetus is fully formed, at birth it will be exactly the same, taking into account the fact that before the end of the term it will gain a few kilograms.

The body of a pregnant woman

During this period, a woman may be disturbed by "false" contractions, which are important not to be confused with real ones, the harbingers are different:

• short duration;
• painlessness.

The movements of the fetus in the trimester become less active, due to the lack of space for the movements of the child, but their number should not decrease. The body is still worried about swelling. Since the stomach has dropped, the higher organs are relieved, there are frequent urges to the toilet and urinary incontinence, which are considered the norm.

Few people manage to avoid back pain at this time, sometimes the sensations are transmitted to the stomach, this is due to the increased size of the uterus. If the discomfort is prolonged, you should make an unscheduled visit to the gynecologist.

It should be noted that premature birth at 35 weeks is not uncommon, they no longer provide danger, and you can understand the likelihood that they can occur by the following symptoms:

1. Slow discharge of amniotic fluid. Usually the fluid comes out immediately in large quantities, just a few hours before the baby is born. Discharges with a lack of color and smell can be distinguished by their characteristic features. This case requires the immediate call of an ambulance.
2. Incessant pain. If there is persistent pain in the abdomen, for several hours, most likely, an early birth is coming.

diet

Due to the formation of the skeletal system of the fetus, pregnant women should take foods with calcium, but it is important not to allow an excess of the mineral, otherwise the hard bones of the baby will be reflected in a more difficult process of childbirth.

• cottage cheese and dairy products;
• vegetables;
• fruit;
• beef;
• a fish.

End of trimester (38-40 weeks)

A few days remain before the birth of a new person, he also feels it, so his heart rate increases to 150 beats per minute. The weight of the fetus can be from 3 kg and above.

Child's condition

The formation of the genital organs has passed into the final stage. The skeletal system continues to form, but if childbirth occurs, this will not be reflected in it. The baby is ready to be born!

feeling pregnant

In the last stages, pregnant women feel exhausted, it is difficult for them to walk, it is uncomfortable to sleep, they suffer from swelling, pain in the back, and calves. Women do not want to do anything, rest is the best pastime for them. Only 5% of women in labor carry the fetus to 40 weeks, most often these are those who give birth to a boy for the first time.

About food

Surely many have heard about the addictions of pregnant women to chalk. This happens from a lack of calcium, in this case it is useful, you can also eat eggshells and other calcium-containing foods.

The most difficult thing is already behind, a pregnant woman needs to be ready to call an ambulance and the upcoming birth any day. The contractions that have appeared in recent weeks cannot be confused with anything, so everything necessary for the maternity hospital should already be collected.

From the following movie, you can learn a lot of interesting things about the third trimester of pregnancy.

The 3rd trimester of pregnancy is a special period in a woman's life, the entry into which will be marked by the final formation of the baby and active preparation for the main event - the birth of a child. During the 3rd trimester of pregnancy, the internal organs and functional systems of the fetus improve.

When does the 3rd trimester of pregnancy begin? According to the obstetric calendar, the third trimester begins at 27 weeks and continues until childbirth. Changes in the body of a woman and the development of the fetus are becoming more noticeable and more obvious every day. The belly, rounded in the second trimester, is now increasing every day, the uterus is expanding, and the child is actively gaining weight. This process creates certain difficulties for the expectant mother, complicates the performance of even the most ordinary daily activities and tasks.

Weight gain in the 3rd trimester of pregnancy is significantly different in speed and volume from previous periods. In recent months, the baby is actively growing, muscle tissue and subcutaneous fat are increasing. In addition to the growth of the unborn child, there is an increase in the volume of amniotic fluid and thickening of the placenta. After 35 weeks of pregnancy, a woman may lose weight and this should not bother her. This fact is explained by the fact that in the prenatal period, the volume of amniotic fluid decreases.

Pregnancy management in the 3rd trimester is reduced to more careful monitoring of the woman's condition and constant monitoring of fetal development. The plan of visits to the gynecologist-obstetrician in the third trimester changes when approaching the expected date of birth:

• up to 30 weeks, a woman visits a doctor once a month;
• from 30 to 36 weeks - 1 time in two weeks;
• from 36 weeks to childbirth - 1-2 times a week.

The visit plan directly depends on the condition of the pregnant woman and her unborn child; if abnormalities or dangerous factors are identified, an individual schedule can be set for each patient. At each appointment, the doctor performs a series of standard obstetric manipulations - listens to the fetal heartbeat, measures the circumference of the abdomen and the height of the uterus, conducts dynamic control of edema, checks the condition of the urinary system and kidneys by urinalysis. If necessary, before each visit to the gynecologist, a general blood test may be prescribed to monitor the condition and functioning of internal organs and systems.

On the eve of the 30th week, a detailed examination of the woman is scheduled. This period marks the beginning of maternity leave. The comprehensive examination includes an extended list of laboratory examinations, ECG, the last scheduled ultrasound, CTG and additional dopplerometry (as prescribed by a doctor).

Normal and anxiety states in the third trimester

The condition of a pregnant woman in the last trimester of pregnancy is complicated not only by an increase in physical stress on the body, but also by emotional experiences caused by the upcoming birth. Some ailments are considered natural during this period of pregnancy, others are a dangerous factor that requires the establishment of causes and correction. Let us consider in more detail what problems a woman may face in the last trimester:

• Headache during pregnancy in the 3rd trimester can be caused by various factors - hormonal changes, metabolic disorders, low blood sugar, dehydration, infectious diseases, stress on the spine and poor posture. If the head hurts in the 3rd trimester of pregnancy intensely and regularly, this may indicate the development of late toxicosis, preeclampsia or preeclampsia. All these conditions are a big threat, they can cause oxygen starvation and subsequent death of the fetus. Whatever the nature of headaches in a pregnant woman in the last trimester, it is very important to find out the cause and exclude possible negative consequences.
• Changes in pressure - in the 3rd trimester, as well as throughout pregnancy, a woman's blood pressure should vary within the normal range from 110/70 to 140/90. An increase or decrease in pressure may indicate violations in the work of internal organs and functional systems. Low blood pressure during pregnancy in the 3rd trimester may indicate problems in the cardiovascular system, lack of vitamins and iron, and stress. Increased pressure occurs with diseases of the heart and blood vessels, kidneys, disorders in the endocrine system. Pressure changes are one of the signs of preeclampsia and require medical correction, diet and rest.
• Abdominal pain in the 3rd trimester of pregnancy is most often caused by stretching of the walls and muscles of the uterus. The second and most likely cause of abdominal pain in the 3rd trimester of pregnancy is uterine tone. Starting from week 36, pain may increase, especially in the pelvic region, and often become spasmodic in nature, this is how training contractions begin. Symptoms of uterine tone during pregnancy in the 3rd trimester are manifested in the form of seizures, during which the abdominal muscles and the muscles of the uterus become very tense, it feels like the stomach becomes stony, it becomes very hard. This condition is accompanied by pain in the abdomen, radiating to the sacrum and lower back. In general, if the attacks are of a short-term nature, then you should not worry, the body is simply preparing for labor. How to relieve increased tone in the 3rd trimester of pregnancy? Doctors recommend not to be nervous, they prescribe bed rest, a diet rich in vitamins and minerals. It is urgent to consult a doctor if the tone of the uterus during pregnancy of the 3rd trimester is accompanied by brownish or bloody discharge. This symptom may indicate placental abruption, which threatens premature birth and oxygen starvation of the fetus.
• Allocations in the 3rd trimester of pregnancy are acceptable, their appearance and consistency matter. Normal discharge during pregnancy should be clear or whitish (leucorrhoea). Such secretions are the secret of the vaginal mucosa, containing dead cells and the natural microflora of the woman's genital tract. If there is no whiter or they are very scarce, you need to consult with your doctor. Brownish bloody and purulent-serous discharges are considered a dangerous type of discharge throughout pregnancy.
• Hemorrhoids are a pathology that women often experience during pregnancy in the 3rd trimester. This disease at the initial stage is manifested by discomfort, itching and pain in the anus, aggravated by defecation and after prolonged sitting. The reason for the development of hemorrhoids is a whole range of factors - increased physical activity, significant weight gain, a sedentary sedentary lifestyle, hormonal and vascular disorders, leading to stagnant processes in the organs and vessels of the small pelvis. Treatment of hemorrhoids during pregnancy in the 3rd trimester is important to start at its first manifestations. During labor, the pathology can become more complex (bleeding, prolapse of nodes, infection and the development of the inflammatory process). How to treat hemorrhoids during pregnancy in the 3rd trimester? The primary stages of hemorrhoids respond well to treatment with rectal suppositories and ointments - suppositories with propolis, sea buckthorn oil, based on shark oil Relief, Heparin ointment. Drug treatment is prescribed for the second and third degree of hemorrhoids as prescribed by the proctologist.
• Digestive and intestinal disorders in the last stages of pregnancy are not common and may indicate serious health problems. An explicable malaise during pregnancy in the 3rd trimester is heartburn. Its appearance is due to a significant increase in the uterus, which squeezes the digestive organs from below, which leads to the reflux of gastric juice into the esophagus. Nausea and vomiting in the 3rd trimester of pregnancy are dangerous signs that may indicate the development of late toxicosis. With such symptoms, you need to urgently contact the gynecologist leading the pregnancy in order to eliminate the danger to the fetus. Constipation in the 3rd trimester of pregnancy is a common phenomenon, it can be provoked by hormonal changes, uterine pressure on the intestines, stress and a sedentary lifestyle. Constipation is easily eliminated with the help of a special diet (high in vegetables and dairy products), correction of the drinking regimen, approved drugs and herbal medicines.
• Edema during pregnancy in the 3rd trimester is common. There are many reasons for the occurrence of swelling of the legs at the moment - the pressure of the uterus on the urinary tract, hormonal changes. If the edema is not too large, then they are easily eliminated with the help of herbal medicine, correction of rest and physical activity. Severe swelling of the extremities and face is a cause for concern and immediate medical attention. These symptoms may be signs of preeclampsia and disorders in the cardiovascular or endocrine system, which can only be identified with the help of special studies.

Diagnosis and research in the third trimester

In anticipation of the maternity leave, a pregnant woman undergoes a full re-examination, control monitoring and assessment of her and her child's condition according to the plan. In the 3rd trimester of pregnancy, the list of tests is almost the same as during the first examination when registering with a antenatal clinic. The complex of studies includes both standard analyzes and additional types of diagnostics:

• Clinical analysis of urine is one of the standard studies (biochemical composition, organoleptic and physico-chemical parameters, microscopic examination of sediment), which gives a general picture of the state and functioning of internal organs. One of the most important indicators is the presence of protein in the urine. A healthy person should not have protein in the urine. In the 3rd trimester of pregnancy, protein in the urine is acceptable in very small doses (up to 0.033 g / l). This is due to emotional experiences, the content of unprocessed protein foods in the diet, mild hypothermia or overheating, increased stress on the kidneys. If the protein content in the urine is higher than normal, an inflammatory process develops in the body. Other studies help to determine the nature and localization of inflammation.
• A clinical blood test is an extended study that determines the qualitative and quantitative composition of blood. The most important indicators in the 3rd trimester of pregnancy are the level of hemoglobin, leukocytes, erythrocytes, ESR assessment. The norm of hemoglobin during pregnancy in the 3rd trimester is 110-140 g / l. A decrease in hemoglobin below the established value during pregnancy in the 3rd trimester indicates a lack of iron and the threat of anemia. With anemia, there is also a decrease in the level of red blood cells. Depending on the degree of anemia, there may be a risk of placental abruption, the threat of premature birth, complications (bleeding) during childbirth.
• A biochemical blood test gives a general picture of the work of internal organs and metabolic processes in the body. The study includes measuring the level of protein, cholesterol, lipids, bilirubin, glucose, enzymes, urea, creatine, trace elements. In connection with the active intrauterine growth of the child and the accumulation of subcutaneous fat in him, special attention is paid to the level of cholesterol during pregnancy in the 3rd trimester. The norm of cholesterol in a non-pregnant woman from 16 to 45 years old should be from 6.02 to 13.8 (the older the age, the higher the allowable rate). In the last trimester, this figure may increase by 1.5-2 times. This is called a natural tolerable increase, a higher level indicates a violation of water-lipid metabolism and requires correction by following a special diet.
• A microflora smear is an assessment of the state of the genital tract and the study of microflora in order to identify pathologically dangerous infectious pathogens.
• A coagulogram is a special blood test, very important during pregnancy in the 3rd trimester, which allows you to assess the degree of blood clotting. Labor activity is often associated with the risk of bleeding, so a blood clotting test is an important indicator for the management of childbirth.
• Tests for TORCH infections (HIV, syphilis, hepatitis B and C) - repeated testing for viral infections is necessary, as many infections have a long incubation period. At the first examination, they could not be found. The placenta can protect the baby from viruses, but when passing through the birth canal, the risk of infection is very high. Therefore, when a virus is detected in the blood, a woman is often offered childbirth by caesarean section.
• A blood test for hormones is a study that allows you to evaluate the hormonal balance and functions of the endocrine system. The main indicators are the level of thyroid-stimulating hormone (TSH), gonadotropin (hCG), vasopressin, progesterone, estrogen. Particular attention is paid to the hormones TSH and hCG. The first indicator allows you to evaluate the work of the thyroid gland. The norm of TSH during pregnancy in the 3rd trimester is 0.4-3.5 mU / p. An increase or decrease in this indicator may indicate various disorders in the thyroid gland. Gonadotropin is the main hormone of pregnant women, the production of progesterone and estrogens, which support pregnancy, depends on it. The norm of hCG in the 3rd trimester is 10,000-60,000 mU / ml. HCG is also involved in the secretion of progesterone and estrogens, its level rises until the very birth, the maximum level is 128,000 mU / ml.

In addition to laboratory studies, instrumental diagnostics is carried out:

• ECG - a traditional study showing the rhythm and work of the heart;
• Ultrasound - in the 3rd trimester of pregnancy is carried out according to the plan at 32-34 weeks;
• CTG - analysis and registration of fetal cardiac activity at rest, during movements and contraction of the uterus, normally at rest, the child's pulse in the 3rd trimester of pregnancy is 120-160 beats per minute;
• Dopplerography is a study of the child's blood flow, which allows you to assess the width of the lumen and pressure inside the vessels, listen to the baby's heartbeat.

If necessary, some types of research can be repeated before childbirth.

Features of the treatment of diseases in the third trimester

The prenatal period is an extremely inopportune time for illnesses, but no one is immune from them. The treatment of any diseases, ailments and pathologies in the 3rd trimester should be approached with caution and special attention. In many women, the protective functions of the placenta at this stage are reduced, so pathogens and drugs can enter the uterine cavity.

Cold

Even a harmless cold during pregnancy in the 3rd trimester can have a negative impact on the health of the expectant mother, affect the condition of the child and the course of labor. What is the danger of a cold during pregnancy in the 3rd trimester? The degree of danger of a cold increases depending on the intensity and nature of the manifestations, as well as on the duration.

The most dangerous cold is considered during the 3rd trimester in the last weeks of pregnancy. If a woman falls ill with acute respiratory infections in any form during pregnancy of the 3rd trimester, starting from the 36th week, she is urgently hospitalized. This precaution is due to the fact that weakened immunity and the gradual aging of the placenta can lead to infection of the amniotic fluid. In addition, a woman's weakened body may not cope well with labor. You should also pay attention to the symptoms of a cold during pregnancy in the 3rd trimester:

• Cough is not just unpleasant, but a very dangerous companion of a cold. This is especially true of dry unproductive and deep chest cough. These types of coughs have a spasmodic effect on the abdominal muscles, the frequent contraction of the muscles of the uterus leads to tone and can eventually cause premature birth. How to treat cough during pregnancy in the 3rd trimester? The safest methods of treating colds during pregnancy include inhalation with medicinal plants. It is important to remember that inhalations should not be hot; if possible, it is better to use a special Nebulizer device or similar devices for this. The choice of composition for inhalation depends on the type of cough, medicinal herbs, fees and essential oils are most often used. It is better not to choose the composition for inhalation on your own, since even herbs and esters can cause allergies. It is better to consult with your doctor. Cough tablets and syrups in the last stages of pregnancy are used in extreme cases, strictly according to the doctor's prescription.
• Sore throat during pregnancy in the 3rd trimester may appear as one of the symptoms of a cold and as a sore throat. If the throat hurts during pregnancy in the 3rd trimester, it should be treated only after examination and consultation with a therapist. The most acceptable method of treating the throat during pregnancy is rinsing with the use of medicinal plants (sage, chamomile, plantain), antiseptic, anti-inflammatory and antibacterial solutions (Miramistin, Chlorhexidine, Chlorophyllipt). As prescribed by the doctor, you can use antiseptics and topical antibiotics in the form of aerosols and sprays. As with a cough, with a sore throat, inhalations give a good therapeutic effect.
• A runny nose during pregnancy in the 3rd trimester cannot be ignored. The danger of a runny nose is that a violation of breathing can make it difficult for oxygen to reach the child. Vasoconstrictor drugs are contraindicated throughout pregnancy, so you can use drops based on plant extracts and essential oils such as Pinosol, Aqua Maris sea water, you can rinse your nose with cold boiled water with the addition of sea salt, essential oils of tea tree, fir, arborvitae, eucalyptus.
• The temperature during pregnancy in the 3rd trimester is a very dangerous condition, as it can provoke placental abruption and premature birth. An increase in body temperature above 37.5 degrees is best avoided. It is strictly forbidden to reduce body temperature with drugs based on aspirin and analgin, from the permitted antipyretic drugs, you can use drugs containing paracetamol (Panadol) and ibuprofen (Nurofen).

Treatment of a cold during pregnancy in the 3rd trimester should be carried out under the supervision of a doctor, strictly following all his recommendations. Treatment of a cold at all stages of pregnancy should be carried out comprehensively, in addition to relieving painful symptoms, it is necessary to eliminate bacterial inflammation and restore impaired protective functions of the body. With the last task, a diet with a high content of various vegetables and fruits, taking vitamin complexes for pregnant women is doing well. Antibiotics during pregnancy in the 3rd trimester are used in extremely rare cases, when the risk of developing a complication of the disease is recognized as higher than the risk of using drugs.

SARS and influenza

Seasonal viral infections can bring a lot of unpleasant moments to any person. If we talk about a pregnant woman, ARVI during pregnancy in the 3rd trimester is complicated by the fact that by the end of the period the woman's body is already weakened by stress and the functions of the immune system are reduced. The procedure for treating ARVI during pregnancy in the 3rd trimester also has difficulties due to the fact that many drugs at this time are contraindicated for a woman.

Viral diseases at the initial stage are accompanied by weakness, runny nose, fever. In the future, a bacterial infection can join the viral infection, which complicates the process of restoring the body. To avoid this, immediately after the first signs of ARVI, complex treatment should be started, which should include antiviral, tonic and immunostimulating agents.

Many antiviral drugs during pregnancy in the 3rd trimester are strictly prohibited, but it is also dangerous to fight SARS only with folk remedies. Antiviral drugs officially approved during pregnancy in the 3rd trimester include the following drugs:

• Viferon - rectal suppositories with immunomodulatory and antiviral effects. Approved and indicated for use to maintain the immune system throughout pregnancy. The main component is recombinant alpha-2b interferon, natural for the human body.
• Anaferon is a homeopathic medicine approved for pregnant women and children. It is used as a prophylactic and immunomodulatory agent.
• Oscillococcinum is also a homeopathic antiviral prophylactic. The product contains extracts of the heart and liver of the Barbary duck, which is a carrier of the influenza virus. When taken prophylactically, it helps the immune system to develop antibodies to SARS.
• Oseltamivir (Tamiflu) is a powerful agent that is effective against many strains of the flu. You can take it only as directed by a doctor in case of severe disease, to eliminate the risk of complications.

The first symptom of ARVI is most often a temperature of 37 degrees and above; in the 3rd trimester of pregnancy, the temperature should not be allowed to rise. You can fight fever with drugs containing paracetamol or ibuprofen. In order not to abuse drugs, you can use acetic rubbing, plentiful warm drink (tea with raspberry jam, honey, natural berry fruit drinks) to relieve the temperature.

Thrush

Thrush during pregnancy in the 3rd trimester develops against the background of hormonal changes and a weakened immune system. The cause of the development of thrush is the Candida fungus, which is found in small quantities in the natural microflora of the vagina. Thrush or candidiasis begins in a state in which conditions are created for the active reproduction of the fungus.

Treatment of thrush during pregnancy in the 3rd trimester is carried out with the help of topical preparations - vaginal suppositories, tablets. Oral antifungal drugs during pregnancy are used only in extreme cases, for example, with the threat of developing generalized candidiasis. How to treat thrush during pregnancy 3 in trimester? Pregnant women can use Pimafucin and Hexicon suppositories, Clotrimazole vaginal tablets. To strengthen local immunity, you can drink a course of probiotics (Vagilak). Reception of specialized vitamin complexes is shown.

Herpes

Herpes during pregnancy in the 3rd trimester is not just an unpleasant, but also a dangerous condition. This is due to the fact that the protective functions of the placenta in the last weeks of pregnancy are already reduced. Activation of the herpes virus can lead to intrauterine infection of the child.

Herpes on the lip during pregnancy in the 3rd trimester should be treated several times during the day with antiviral drugs based on acyclovir (Gerpevir, Zovirax). Viferon ointment has proven itself well in the fight against viral rashes on the skin. To get rid of herpes as soon as possible, you need to use the ointment often, every 1-1.5 hours, after removing the previous layer from the skin surface. To restore immunity, it is recommended to enrich the diet with fresh vegetables and fruits.

Diet

Nutrition in the 3rd trimester of pregnancy should be treated with special attention, since this period is simultaneously associated with several problems:

• active weight gain;
• swelling of the limbs;
• iron deficiency and folic anemia;
• phlebeurysm;

Pregnancy is an important period in the life of every woman. What is happening at this stage? What week does the 3rd trimester start? How to develop a menu? We will answer all these questions in our article.

Pregnancy and its course

Becoming a mom is a big responsibility. It is for this reason that the appearance of the first child raises a huge number of questions. How to protect yourself? What can be consumed so that the child develops normally?

It is worth noting that such questions do not arise with a second pregnancy. An experienced woman already knows what and how to do so that the baby is born healthy.

There are several main stages of pregnancy:

• 1st trimester;
• 2nd trimester;
• 3rd trimester.

Thus, the entire period of bearing a child is clearly divided into trimesters. Before determining which week the 3rd trimester begins from, let's discuss the first two.

First trimester of pregnancy

As a rule, not every expectant mother knows the exact time and day of conception. It is for this reason that doctors consider the first trimester of every woman with special care. This will allow you not to miss important events in the development of the fetus.

The first trimester starts from the 1st week and lasts until the 13th. It is considered the shortest, although for some women it lasts quite a long time. This fact is due to subjective sensations and changes in the psyche. The body of the expectant mother during this period adapts to a new state.

Note. In the early stages of pregnancy, a woman is extremely attentive to her body.

And this is right, because not only emotional outbursts appear, but also other mental states. Unusual ones are also observed. They can be painful, because the egg is already starting to grow, and the fetus in it is developing. There may be tingling in the lower abdomen. All this is considered normal to a certain degree of pain, especially in the early stages of pregnancy.

Important. If there is pain in the abdomen, doctors recommend a physical examination.

This will help to identify various pathologies of pregnancy and eliminate them. During the course of the first trimester, a woman must register with the clinic. As a rule, staging starts from the 4th week.

Features of the first trimester

During this period, the birth and initial development of the baby takes place. The fertilized egg travels through the fallopian tubes. In the uterus, she is 7-8 days after conception. Then the active formation of the embryo begins. By the end of the third week, the size of the unborn child is 2 mm. On the fourth - the heartbeat is heard in the embryo.

In the sixth week, the rudiments of the nervous and digestive systems are formed. Also during this period, the initial elements of the brain begin to develop. At the eighth week, the baby already has limbs, a head and a face.

Note. At this stage of the development of the child, doctors recommend taking general tests and doing an ultrasound. This will identify various deviations in the development of the fetus and eliminate them in a timely manner.

The ninth week is the development of the kidneys. Already at the 12-13th week, the baby actively bends and unbends his limbs.

The dangerous periods of this trimester are 8-12 weeks. If a woman's placenta does not develop, the fetus may die. To prevent these irreversible consequences, it is necessary to constantly be observed by a doctor. Now such a deviation in the body of a woman is perfectly treated with the help of medicines.

Second trimester

It is considered the most interesting stage of pregnancy. What week does the 3rd trimester start? If the second trimester starts at week 14 and ends at week 25, then it is from the last starting point that you can prepare for childbirth. At week 26, the last trimester begins.

During this period, a woman's mammary glands swell. In some cases, there are pain syndromes in the abdomen. This is due to the fact that the child develops stably and correctly, and the uterus increases in size. To fit it, the internal organs are slightly moved apart.

Advice. For any pain syndromes, you should consult a doctor.

In the second trimester, it is already possible to accurately determine the sex of the unborn child. The fetus begins to move, which sometimes causes a lot of trouble. Especially at night.

The baby receives from the mother all the necessary vitamins, enzymes and food. Right now, a woman begins to eat much more food. It should be borne in mind that normal weight gain during pregnancy is 8-12 kg. Sometimes it can reach up to 14 kg. It all depends on the physique of the woman and her body.

Features of the second trimester

This period can also pass with the development of various pathologies, both the placenta and the baby. Sometimes there is the appearance of discharge, pulling pain in the lower abdomen. To avoid negative consequences, you should immediately consult a doctor.

third trimester

At this time, the woman's body is effectively preparing for labor. What week does the 3rd trimester start? From the 25th week, you can already count the days until the baby arrives. The end of the 3rd trimester is the 42nd week.

By the 27th week, the baby's weight is about 1 kg, and the height is 35 cm. When a woman already has 28-29 weeks of pregnancy, the baby is effectively gaining weight, subcutaneous fat appears. You can forget about restful sleep, because the baby is actively moving.

Dangerous weeks during pregnancy in the 3rd trimester

If the development of the fetus proceeds normally, you should not be afraid of anything. Especially under the supervision of an experienced doctor. Despite this, it is worth being vigilant, because the new dangerous period is 28-29 weeks of pregnancy. It can last up to the 32nd week. It all depends on the characteristics of the female body.

The doctor must assess the condition of the placenta and intrauterine development of the fetus. This can be done with an ultrasound. If there are any deviations, prescribe medication. It will not harm the baby in any way and will help maintain the pregnancy.

It is worth noting that at this stage, in some cases, premature births are observed. The child can already survive, especially with qualified help from doctors.

Nutrition during pregnancy

In order to correctly compose the diet of the expectant mother, it is necessary to clearly know when the trimesters of pregnancy begin and end by weeks (the table is given above).

In the first trimester, the diet of a pregnant woman is no different from the usual. It is necessary to follow some recommendations that will help to avoid toxicosis.

Green salads with vegetable oil should be included in the daily diet. It is also necessary to eat fish, which is rich in phosphorus and other minerals. It is necessary to provide your body with iodine, vitamin C and folic acid. They contribute to the proper development of the fetus at an early stage.

It is better to exclude coffee from the diet, as it contributes to high blood pressure. It is better to drink green tea, but also in limited quantities - up to 3 cups a day.

Important. The use of citrus fruits, exotic fruits and berries should be minimized, as they are potential allergens.

Menu - 3rd trimester of pregnancy:

• vegetables and fruits rich in vitamins;
• special vitamin complexes based on folic acid;
• minerals - iodine, calcium;
• vegetarian dishes;
• boiled poultry and fish;
• low-fat meat broths;
• bakery products in limited quantities.

Don't forget to drink fluids. It is better to limit its amount to 1-1.5 liters, since the kidneys already serve the body of not only the expectant mother, but also the baby. We must try to ensure that the child is born healthy.

Sometimes it is difficult for pregnant women to figure out which week the 3rd trimester of pregnancy begins and how long it will last. There is nothing complicated here, but inexperienced expectant mothers may need clarification.

How to keep count

It may seem difficult to clearly understand when exactly the third trimester of pregnancy begins and how long it will last. This is because the beginning of it, in accordance with the accepted classifications, may fall on different dates, depending on which classification the gynecologist leading the pregnancy uses.

The entire gestation period is not divided exactly into equal parts. The division is carried out depending on the characteristics of the course of pregnancy approximately as follows:

1. First trimester. During this time, the formation of systems and organs of the embryo occurs.
2. Second trimester. The grown embryo is now called a fetus, which continues to grow and develop.
3. Third trimester. The child is gaining weight.

While the third trimester of pregnancy lasts, the child is mainly engaged in the accumulation of subcutaneous fat. In addition to the usual fat, which everyone has, a special one is still accumulating - brown, which the child will spend in the first few days after birth.

Thanks to this reserve, the baby will receive both the warmth that he needs and the nutrients. Such fat accumulates in the area of ​​​​the shoulder blades. In the same period, the organs will be improved, the systems of the child's body will be strengthened.

For example, the baby's respiratory system, although fully formed at this point, is not perfect. If it happens that the birth of a child will occur at the beginning of the trimester, he will be given special drugs that will not allow the lungs to stick together.

The immune system during this period also did not have time to fully form, so the child's body is easily amenable to a variety of infections.

How to count during pregnancy

According to rough calculations, the first of the trimesters is usually the first three months of pregnancy. The next three are the second trimester. In the third are the remaining months. If you perform calculations by weeks, it turns out a little differently, but the options will not go beyond one month.

From what week can the third trimester be considered to have begun, if we do not calculate by months? Many of the classifications consider it starting from the twenty-fourth week, in other versions - the twenty-sixth or even the twenty-eighth week.

But keep in mind that doctors usually calculate the gestational age using the concept of a week. As for such calculation categories as month and trimester, they are used much less frequently. Therefore, when determining the trimester, it is better to focus on the classification used by the gynecologist leading the pregnancy.

How is this period different from others?

The differentiation of pregnancy into periods is carried out because there is a difference in the approach to certain points in the course of pregnancy. This makes it possible to more closely monitor the condition of the expectant mother. For example, if a lady happens to get sick in the first months after she becomes pregnant, if possible, you should avoid taking medication. But during the third trimester of pregnancy, everything is somewhat simpler - the placenta is able to fully function and protect the child's body from unnecessary substances and harmful microorganisms.

For a variety of procedures that must be carried out during pregnancy, the division into trimesters is also important. It will be easier and more convenient for the doctor to work with determining the condition of the woman and prescribing drugs or procedures.

The condition of a woman in the last weeks of pregnancy

When the last trimester of pregnancy begins, it is time for a woman to get ready for maternity leave. At this time, she has already gained a lot of weight, her tummy is quite large, she moves harder, it becomes uncomfortable to sit or stand. At this stage, more time should be devoted to rest and sleep. It's time to forget about giving yourself completely to work.

At the end of pregnancy, a woman gains a lot of weight. You should be more careful about your diet, when overeating, not only the expectant mother will get better, but the baby will also gain considerable weight, and this seriously complicates childbirth. In mothers, excess weight often causes hypertension, varicose veins. Sex in the third trimester becomes a painful topic for many. It is necessary to get a consultation of the gynecologist leading the pregnancy about this.

How long is the trimester

Women are interested not only in when the last trimester of pregnancy should begin, but also when it will end.

The timing of each pregnant woman is individual, this must be remembered. Sometimes the birth comes a little earlier than it should, sometimes the pregnancy is postponed for a couple of weeks. This is not out of the norm. The moment of conception in most cases is determined approximately, so it is impossible to conclude with complete certainty on which day the baby will be born. With a normal pregnancy at 40 weeks, the last trimester can be 16-12 weeks.

Sometimes labor starts early. To avoid this, you must follow some important rules. This is, first of all, control over physical and emotional stress. Secondly, it is necessary to observe the regimen and be attentive to your own nutrition. It is important to visit your doctor regularly. At the slightest complication, the doctor will be able to notice the problem and prescribe treatment.

The child during this period grows more and more and gains weight. His organs of hearing and vision are being improved. From the increasing load, the mother has more frequent back pain, training contractions appear, the uterus can put pressure on the nerve endings, which is why constant medical supervision is important. If necessary, the woman will be taken to the hospital in a timely manner, where, with the help of medical procedures, her condition will be stabilized.

This is a really difficult period, and the difficulties are only increasing day by day. It is at this time that gestosis, late toxicosis can develop, which is manifested by troubles with pressure and frequent edema.

Chronic diseases, respiratory complications, heartburn can also manifest in full force. During this period, the doctor, with a particular severity of the condition, may prescribe the stimulation of premature labor to the woman, if this should save the situation with her health.
