1st trimester

First 3 months (12 weeks) period

The first sign of pregnancy is the absence of menstruation.

When pregnancy is first learned, you should quit your bad habits such as alcohol and cigarettes as it will be risky during pregnancy.

You should drink plenty of water. It is recommended to drink 2-3 liters of water per day on average.

In order to support the development of the baby's brain and nervous system, adequate folic acid intake of the mother is important during this period.

If it has not been started before, 400 micrograms of folic acid per day is started.


3. Week of Pregnancy

first 4 weeks of pregnancy

Since the weeks of pregnancy are counted starting from the first day of your last menstrual period, it will be 4 weeks when the fertilized egg implants in the uterus. From the moment the fertilized egg implants in the uterus, beta-HCG hormone increases in the blood. Before four weeks, there can be no talk of a pregnancy or baby in the womb. Since ovulation occurs 2 weeks after the last menstruation, fertilization occurs on these days. Therefore, in the days called 1st or 2nd week of pregnancy, there is actually no pregnancy yet. The third week passes with fertilization and making its way to the uterus. However, in the 4th week, the fertilized egg reaches the uterus and settles there. In the fourth week, the beta-HCG test that you will have in the blood will confirm whether you are pregnant or not. During this period, there may be a small amount of bleeding, inguinal pain as if it will be menstruation, breast tenderness, fullness, weakness, drowsiness and frequent urination. During this period, you should definitely consult a doctor. In the fourth week, transvaginal USG (TV-USG) does not show the gestational sac yet, but the thickness of the endometrial (inner lining of the uterus) that supports pregnancy is seen. During this period, the endometrial thickness is 15 mm and above, and beta-HCG is around 100 IU/L. Visualization of the gestational sac by TV-USG, 5-6. finds weeks.

5. Week of Pregnancy

In the fifth week, beta-HCG is approximately 600 IU/L, and gestational sac is approximately 10 mm in TV-USG. Yolk Sac is 2 mm in diameter. The head-rump length (CRL) at five weeks of pregnancy is around 2-3 mm. It can be seen with TV-Ultrasound. It is seen near the yolk sac. We call this image  solitaire ring image. Even if it is not seen, it should not be worried and should be looked at again in the future. Circulation of the embryo begins on the 21st day after fertilization. For this reason, heartbeats can sometimes be seen with TV-USG. The amniotic sac (water sac) and placenta develop and exchange between mother and baby accelerates. Blood cells are formed and the passages in the channels increase. The balloon-like structure next to the baby is called the "Yolk Sac (yolk sac)" and the baby feeds the yolk sac during these weeks until the mother begins to feed. The baby's cardiovascular, brain, nervous and other organ systems begin to develop.


In the 5th week of pregnancy, some changes may occur in the mother, both physically and psychologically, due to the rapid change in hormones. The mother is more tired than usual, is sluggish and sleeps all the time. Tightness in the breasts, tenderness and darkening of the nipples may be the first symptoms. The urge to urinate frequently develops due to the enlargement of the uterus. There may be groin pain and cramps similar to menstrual pain. These are normal. Sometimes there may be spotting or light bleeding. Even if it is small, when bleeding occurs, it is necessary to consult a doctor because of the risk of miscarriage. Gas and digestive problems may develop. Often morning sickness may be present.

6. Week of Pregnancy

In the sixth week, beta-HCG is observed at 5200 IU/L. At six weeks of pregnancy, the baby's heartbeat can be easily seen and heard with TV-USG. Embryo heart rate is around 85-100 beats per minute. Gestational sac is 15-16 mm. Yolk Sac is 4 mm in diameter. Head-butt length (CRL) is 4 mm. In the sixth week, the baby's umbilical cord forms. The eyes, ears, and oral cavity appear on the larger-than-normal head of the embryo. The hip part is also revealed in the same way. Arm and leg buds are formed.

The liver, lungs, pancreas, inner ear, stomach, esophagus, and even the mouth opening appear as more distinct outlines. The first structures that will form the respiratory and digestive system of the baby become evident.



The placenta appears, which provides all the exchange between you and your baby. With the increase in the hormones secreted during your pregnancy, your nausea and smell sensitivity increase this week. You may feel nauseated, especially in the morning. Sometimes vomiting occurs and these complaints may continue until the 12th week. You may experience emotional fluctuations due to changes in hormones. Most pregnant women feel lonely and tired. Frequent urination becomes more evident due to the enlargement and pressure of the uterus. You may have groin pain, this is normal as long as there is no bleeding. Indigestion, constipation and stomach ailments will be closely related to the foods taken during this period.

7. Week of Pregnancy

This week, beta-HCG is monitored at a level of approximately 26,700 IU/L. Embryo heart rate is 120-160 beats per minute on average at the 7th week of pregnancy. At seven weeks of pregnancy, the baby's head-rump length (CRL) is around 9-10 mm. The gestational sac is 22-24 mm. Its arms and legs, which are in the form of buds, continue to take shape. However, arms, legs and fingers did not form separate from the body. Organs such as the brain, spine and thyroid glands, great vessels, eyes, stomach, intestines, kidneys, lungs, liver, gall bladder and pancreas have begun to develop. Eye sockets, ears become more prominent and eyelids appear. Bone structures of the arms and legs begin to develop, but are not yet fully formed.


Breast enlargement and tenderness continue. Different complaints such as low blood pressure and headache may be experienced. Nausea can begin during these weeks, especially right after getting up in the morning, and can be active throughout the day. During this period, some pregnant women may gain 1-2 kg, while others may lose 1-2 kg due to vomiting. Especially if you have nutritional problems due to nausea or frequent vomiting, you should definitely get nutrition and some medication recommendations from your doctor. To reduce nausea, frequent and less meals, dry non-fat foods, crackers, chickpeas and crackers may be suitable foods.

8. Week of Pregnancy

The baby's body movements can be seen on USG  , but it takes the 18th week for the mother to feel it. At eight weeks of pregnancy, the head-rump length (CRL) of the embryo is about 15 mm. Its weight is about 2 grams. In the 8th week of pregnancy, the nasal tip, eyelids and lower jaw of the embryo become prominent. In this week, the baby's arms increase in length, fingers and elbows begin to form. The toes are still stuck together. Nerve conduction of his arms occurs. Leg buds grow and toe notches begin to form. The shaping of the eyes, nose and ears on the face continues. The trachea separates from the esophagus. Kidneys develop. The spinal cord also continues to develop. Bones begin to harden. Under the palate, buds begin to form, which will later form the teeth. The baby's back muscles become prominent around the spine. The veins in the umbilical cord that connects the mother and the baby begin to function.


This week, you may experience pain and cramps in your abdomen and groin from time to time due to the enlargement of your uterus. Oily skin, acne and exfoliation may occur. Due to increased pregnancy hormones, the digestive system works slowly. This leads to indigestion, constipation and gas complaints. Therefore, gassy and uncomfortable foods should be avoided. You may still have complaints of frequent urination along with nausea.

9. Week of Pregnancy

At nine weeks of pregnancy, the baby's head-rump length is  (CRL)  23-24 mm, and its weight is about 2-3 grams. The ninth week is the last week of the embryonic period. After this, the fetal period will begin and the embryo will be called a fetus after the tenth week. In the ninth week, the face of the embryo becomes more pronounced. The eyes become prominent, the retina forms, the eyelids develop, the auricle, nostrils, nasal tip and tongue begin to form. Cartilage and bone tissues are formed. Fingers are formed but still attached. The testes or ovaries, the structures that will form the internal genital organs, begin to develop. The ridge that will form the structure of the baby (girl - boy) becomes evident, but the genitals have not yet developed enough to understand the gender. The gender of the baby cannot be told. The intestines, which had protruded around the baby's umbilical cord in the first stages of formation in the previous weeks, now begin to migrate into the abdomen. Heart valves are formed. The baby starts to swallow for the first time this week and drinks amniotic fluid (the water the baby is in). In this week, it is seen that the baby is moving.


During these weeks, the waist thickens and the clothes begin to tighten. Apart from your nausea, you may have heartburn, gas and indigestion. For a healthy pregnancy, the mother should have a regular and balanced diet. Daily calorie intake should increase by 250-300 calories compared to pre-pregnancy. Foods containing protein, fruits, vegetables and calcium should be taken. With the effect of increasing hormones during pregnancy, maternal psychology may deteriorate. The susceptibility to depression increases. There may be episodes of emotionality, irritability, and even crying. Spouses and relatives should be more understanding. Again, weakness, fatigue and drowsiness continue.

10th Week of Pregnancy

At ten weeks of pregnancy, the baby's head-rump length (CRL) is about 30 mm, and its weight is 4-5 grams. While the baby is called an embryo until this week, it is called a fetus from the 10th week until birth. Although its development continues in the following weeks, all vital organs have completed their main development by the 10th week. The heart is developed and able to provide blood circulation regularly. The digestive system and reproductive organs are more developed. Body folds, elbows, knees, toes, and fingers are quite prominent. Muscles began to strengthen and mobility began to increase. Movements are clearly visible with ultrasound. The baby has acquired the reflex to hold an object that touches his hand. The auricle and upper lip are shaped. The baby makes swallowing movements, swallows the amniotic water and starts urinating for the first time. 
The most critical process in the development of the baby's organs and tissues is over. Because the first 10 weeks are the most critical and sensitive period in baby development. This period (first 10 weeks of pregnancy) is the period when the baby is most sensitive to drugs and toxic substances.


Emotional fluctuations are among the prominent complaints this week. By the end of the third month, when beta-HCG levels peak, this over-emotional sensitivity will decrease significantly. It is important for the pregnant woman to feel comfortable and peaceful for the continuation of the pregnancy. Due to increased blood flow during pregnancy, body temperature is felt more. Heat intolerance increases After this period, non-tight cotton underwear and bras that do not tighten more comfortably due to breast enlargement should be worn. Flat and comfortable shoes should be preferred instead of pointy-toed and high-heeled shoes.

11. Week of Pregnancy

In the eleventh gestational week, the baby's head-rump length  (CRL)  approximately 40-41 mm, and its weight is 7 grams. The size of the baby's head is half its height. The period from the eleventh week to birth is called the fetal period. All details of the fetus can be seen on ultrasound imaging. During these weeks, blood circulation begins between the baby and the mother's womb and the placenta (the baby's partner) begins to function. The baby urinates, so the amniotic fluid in the gestational sac also increases. The baby's heart, blood vessels, brain, nervous and skeletal systems have become functional. The baby's hair and nails begin to develop. From the 11th week, the baby enters the rapid growth and maturation process with the onset of the fetal period and is prepared for birth.


In these weeks, the feeling of nausea and vomiting may continue, although it may decrease. As always, great care should be taken with food and drink. Headaches may increase due to hormonal changes. In order to prevent headaches, it is necessary to stay away from stress, sleep regularly and eat regularly. It is considered normal to have a white-transparent odorless discharge, which may be present throughout the entire pregnancy, and which may be excessive in amount. If color, odor or itching is added to this, consult your doctor!

12th Week of Pregnancy

At the twelfth gestational week, the baby's head-rump length (CRL) is approximately 52-53 mm, and its weight is about 15 grams. The fetus now looks like a complete baby. In this week, all the baby's organs are formed. All these formed organs will continue to grow until birth. Fingers and toes are separated from each other. Nails continue to form. Nervous system and muscular system are strengthened. The external genital organs of the baby begin to take shape and become distinguishable by ultrasound within a week or two, whether it is a boy or a girl. By the end of the twelfth week, the first trimester of pregnancy is over.


At the end of twelve weeks, the mother can gain about 1-2 kilos. Rarely, he may not have gained any weight during these months. The complaints of nausea, vomiting and breast tenderness gradually decrease. As the baby grows in the uterus, the uterus now rises above the pelvis. The waist is noticeably thickened. Black lines (linea nigra) begin to appear on the anterior abdominal wall, below the navel. As the baby's nutritional needs increase and the mother's feeling of nausea decreases, feeding is relieved and weight gain begins. Headache, heartburn, constipation complaints may continue. Along with constipation, hemorrhoids may be experienced. In order to prevent these complaints, plenty of fluids should be taken and fibrous foods should be consumed throughout the pregnancy.

At the thirteenth gestational week, the baby's head-rump length (CRL)  approximately 67-68 mm, weight is 16-20 grams. This week, the baby's face starts to look like a normal baby face. The baby's vocal cords, palate and teeth begin to form. Insulin can be secreted from the pancreatic gland and bile fluid from the liver. With the advanced ultrasound device, the eye lenses can be seen and their gender can be selected. While the baby's eyes were previously far apart, this week they begin to approach each other, the ears move towards their normal places. In this week, the sex of the baby is developed enough to be told by looking at the external genitalia. The baby swallows the amniotic fluid in which it is present and expels it again as urine, and the urine mixes with the amniotic fluid. During this period, as the muscles and joints get stronger, their movements increase a lot.


With the 13th week of pregnancy, the second trimester begins and the mother enters the most comfortable period of pregnancy. Nausea, vomiting and irritability are reduced. Fatigue and drowsiness ends. The mother regains her old energy. Heartburn and burning sensation may persist. The uterus grows rapidly and as it grows, the organs in the abdomen will move slightly from their normal places. For this reason, there will be tension in the muscles and fibers that hold the organs in place, which will cause groin pain. This is normal pain. Due to the tension in the abdominal wall, cracks may occur in the abdomen and it is recommended to use special anti-crack creams to prevent this. Unfortunately, cracks that may occur during this period never heal. For this reason, it is necessary to take precautions before it occurs, consume plenty of liquid and fiber foods, and pay attention to weight gain by doing adequate gymnastics. It should not be forgotten that cracks may also be related to the skin structure. During this period, there may be spots on the skin due to increased estrogen. This is most common in the nipples, abdomen, and groin area. It may be a percentage in some pregnant women. Skin darkening can also increase with sunlight and ultraviolet. Pregnant women should not be exposed to too much sun and should use products with protection factor. Skin darkening disappears after childbirth.

While the shape of the baby and especially the head has always been curved in all ultrasound images until now, the baby can stand upright and raise its head in the 14th week of pregnancy. The baby can take deep breaths and swallow. It feeds on the nutrients taken by the mother and oxygenates her blood with the air she breathes. His muscles are now very strong. Its entire body is covered with colorless and fine hairs. The baby's neck gets longer and his chin begins to move away from his chest. The baby begins to move his hands and arms. The baby's heartbeat can be heard with the doppler device. The baby's digestive system begins to move as if digesting the food he eats. The baby has very thin nails. The baby can suck his thumb during these weeks. The baby's bone marrow begins to produce blood cells.


In the 14th week of pregnancy, heartburn increases due to the escape of stomach acid, called reflux, into the esophagus in the mother. In such cases, it is recommended that pregnant women do not bend over after meals and do not go to bed immediately. If they are going to sleep, it is recommended to keep the pillow a little high. With these measures, stomach acid can be prevented from reaching the mouth. Breasts continue to grow. In fact, yellow and cream-colored milk called colostrum may start coming from your nipples. The mother may meet with low back and back pain this week. Due to the relaxing effect of hormones in pregnancy on your whole body smooth muscles, constipation may occur during these weeks.

The baby's eyelids are tightly closed during these weeks. He drinks amniotic fluid regularly and may hiccup sometimes.


Your pregnancy is now starting to show from the outside. You can apply anti-stretch creams and drink plenty of water to avoid stretch marks on your stomach. There will also be an increase in waist and back pain. During pregnancy, the joints between the bones in your hip area relax in preparation for birth, and the weight of the uterus increases and the center of gravity changes. As a result, body shape and gait change, and changes made to compensate for these changes cause back pain. To reduce back pain, lie down with your knees pulled towards your stomach, facing one side. Place a cushion between your knees and under your stomach. Do exercises to strengthen the abdominal muscles. During this period, gingival bleeding may begin, which is normal.

This week, the placenta (baby's partner) weighs the same as the fetus (baby)  . The baby's external genitalia (male or female gender) can be seen very easily. Nerve conduction is strengthened thanks to myelin (the substance that covers the nerve fibers). The baby becomes sensitive and may even react to light.


The mother's womb is now easily visible from the outside. Recognition of pregnancy from the outside varies. The reasons for this are the mother's body structure and the number of births. Compared to the first pregnancy, the second and third pregnancies become evident earlier due to the weakening of the abdominal muscles. Some pregnant women say they feel the baby's movements this week. Baby movements are usually 19-20 in the first pregnancy. felt during pregnancy.

In the seventeenth week, the baby's subcutaneous fat storage increases. For this reason, the baby begins to gain weight faster. Fat storage is important for baby's temperature control. The baby can do reflexes such as blinking, swallowing and sucking. The transformation of cartilage into bone tissue continues. His heart can pump 25-30 liters of blood and beats 120-160 per minute.


The uterus grows below the belly button. As a result, the body naturally begins to expand. Therefore, comfortable clothes should be chosen. Likewise, the breasts become larger.

The baby is about 28.5 cm long and weighs 501 grams. The baby gets bigger and chubby as it goes on. The newborn begins to look like a baby. He hears better because his bones in the middle ear have hardened. Eye pigments begin to form. The pancreas develops and secretes insulin more regularly. The whole body of the baby is densely covered with fine hairs (lanugo).


As the load on the waist and back increases, there is an increase in waist and back pain. The waist crease may turn a little more inward. These pains are related to the change in the center of gravity. Leg cramps can be seen frequently in pregnant women who are experiencing these weeks. These cramps can be severe enough to wake the mother from sleep, especially at night. Calcium and magnesium intake, drinking plenty of milk will reduce these complaints and the frequency of cramps.

24th Week of Pregnancy

The baby is about 30 cm tall and weighs 600 grams. In this week, the development of the respiratory tract in the lungs accelerates. Surfactant production begins in the lungs. Surfactant covers the inner surface of the air sacs that provide ventilation in the lungs and is the substance that prevents the vesicle walls from sticking together after evacuating the air in the vesicle. Babies have almost no chance of surviving because their lung development is very low before 24 weeks. The baby begins to gain consciousness. Its memory begins to store information. Mental functions will develop more and faster this week. Your baby continues to gain weight rapidly. This causes an increase in muscle and adipose tissue. The sense of taste develops. The nostrils open.

At the twenty-fifth week, the baby's height is about 34.6 cm, and its weight is 660 grams. The spinal structure has been strengthened and the nerve structure in the spinal cord has developed. The palate is fully formed. Blood vessels form in his lungs. Sweat glands, which are very important for the body, develop. The baby begins to make catching movements. The baby starts to hiccup frequently.


Varicose veins in the legs, waist and back pain may occur due to the pressure of the growing uterus and the deterioration of circulation. In some pregnant women, there may be pain in the whole body, including the fingers. In order to reduce these pains, one should change positions frequently while standing, lie down whenever possible and take a shower with warm water. Vaginal discharge may increase during these periods. Odorless and colorless discharge is normal during pregnancy.

The baby's eye color also develops, but the true eye color becomes apparent 4-6 months after birth. It is sensitive to sound and light. It responds to you when you touch it from the outside  or speak because it will hear you. Hand and foot prints begin to form, which distinguishes your baby from other babies. Lung continues to develop. A substance called surfactant is made in the lung air sacs. This development is beneficial but not sufficient for the baby to be able to breathe in case of premature birth.


You may notice that your eyes are quite sensitive to light this week. Dry eye due to pregnancy is a common complaint of many expectant mothers. You can use artificial tear preparations to overcome the problem. You may have gained about 6-7 kilos by this week of pregnancy.
