Waiting for the birth of a new life is an exciting time in every woman's life. But any expectant mother is worried about how the pregnancy should go and how the baby should develop in her stomach. In this article, I will consider the basic facts about how the 19th week of pregnancy goes. Photos of the fetus will also be posted below.

Second trimester of pregnancy

From the first weeks after the conception of the fetus, changes occur in the body of a woman. But already in the second trimester (from 13 to 14 weeks), the condition becomes more stable. The most common symptoms are morning sickness and dizziness. Pregnancy of 18-19 weeks proceeds more calmly, the fetus has already taken root in the mother's body and continues to develop actively. However, you should be responsible for your position, avoiding stress, physical exertion and injury. At this interval, there is a small risk of preterm labor.

How to correctly calculate the gestational age and due date

Most of the ladies who first learned about their situation, begin to calculate the date and date of delivery. But you should know that there is also an obstetric gestation period, according to which the pregnancy lasts not nine months, but 41 weeks, that is, more than nine. The gynecologist begins the countdown of the course of pregnancy from the date of the beginning of the last menstrual cycle. Usually the difference between the obstetric period and mommy's calculations is about two weeks. Following these rules, it is quite easy to find out the approximate day of the baby's birth.

19 week of pregnancy, how many months are left before delivery according to the obstetric calendar? After doing the calculations, it turns out that this is the end of the fifth month, therefore, there are four more left before the birth. However, the development of the fetus is determined by the embryonic period, that is, the countdown goes from the week when the conception occurred. The fetus must correspond to 17 weeks of development.

Pregnancy 18-19 weeks. Growing belly features

Before the beginning of the second period of fetal development, the stomach is almost invisible, since the baby is still very small and the uterus has only slightly increased in size. The belly at the 19th week of pregnancy becomes already much larger, which limits the expectant mother in freedom of movement. It becomes difficult to bend over, stay in one position for a long time and sleep. The uterus begins to put pressure on the internal organs of the pregnant woman. Very often there are heartburn, constipation and the urge to urinate becomes more frequent. Great attention should be paid to the food consumed, since from this moment the doctor begins to strictly monitor the weight of the woman,carrying a baby. It is important to take a responsible attitude to the position occupied during sleep. It is undesirable to sleep on the stomach or back, because this can harm the fetus. In the "lying on the stomach" position there is a risk of damaging the fetus, and in the "lying on the back" position there is a high probability of pressing down on the aorta through which oxygen enters. You should rest, lying on the side where the baby is located.

At every medical examination from the second trimester onward, the doctor should measure the abdomen. Its volume directly depends on the size of the fetus, uterus and the amount of amniotic fluid. Of course, every woman during childbearing has her own individual characteristics, depending on her physique and body weight before pregnancy. But there are certain acceptable norms.

The belly at the 19th week of pregnancy, when measured vertically, reaches 18-20 cm. The uterus is already beginning to rise to the navel. This data is only for singleton pregnancies.

If the doctor notices deviations from the norm, then the pregnant woman is sent for additional examinations. Since the cause of an increase in the abdomen may be too much amniotic fluid or other abnormalities.

What changes occur in the fifth month of pregnancy

A woman who is expecting a baby is already getting used to her condition by the fifth month. Time flies, the first period is over, the 19th week of pregnancy has come. What happens to the child's bodythis moment?

Within five months, the fetus developed from an embryo to a little man. At this time, the baby has already formed arms, legs, fingers, auricles, the shape of the head and parts of the face. The respiratory, digestive and nervous systems, the subcutaneous layer, and the rudiments of teeth also continue to form.

If before this period, mommy has already felt the first movements of her child, now his movements will become more confident and clear. And some future mothers will only have to rejoice at the first pushes and kicks. The child's brain is already actively developing. The embryo begins to move in the abdomen, very often changes its position. In connection with the beginning of brain activity, fetal movements become more concentrated. There may be a reaction to the sounds of the voice of the parents and the touch of hands on the stomach.

Second fetal ultrasound

As a rule, in the second trimester of pregnancy, in addition to all the already familiar examinations, an ultrasound examination of the fetus is also performed.

At the first planned examination, the doctor confirms the presence of a normal pregnancy (not intrauterine or frozen), clarifies its term, determines the age of the fetus and the sex of the child (the probability of determining the sex of the fetus is very low).

An ultrasound procedure at the 19th week of pregnancy is performed to identify possible pathologies in the fetus and examine its anatomical development. This study also determines the position of the fetus in the womb, which plays a big role in howundergo childbirth. Also, using the apparatus, the doctor performs fetometry, that is, determines the size of the circumference of the head and abdomen, bones of the arms, legs, hips, shoulders. The symmetry of external and internal organs is visible. The determined gender of the child has a probability of up to 90%.

Based on the data recorded by the specialist, it is concluded that the development of the fetus corresponds to its embryonic age. In addition to studying developmental parameters, the doctor examines the condition of the uterus and placenta. If pathologies are detected, the gynecologist, based on the results, makes a diagnosis and prescribes treatment.

Norms for ultrasound indications.

• BPR - from 40 mm to 50 mm;

• LZD - from 53.5 mm to 60.5 mm;

• Exhaust gas - from 140 mm to 180 mm;

• DB - from 25 mm to 35 mm;

• DW - 23mm to 31mm;

• DP - from 20mm to 26mm;

• Coolant - from 125mm to 155mm;

• NC - from 5.2mm to 8.0mm;

• height - about 22.1 cm;

• weight - from 230 gr to 320 gr.

During the second ultrasound examination, the 19th week of pregnancy comes to an end. A photo of the child can be obtained from the doctor. The picture already shows a formed little man, all parts of the body are clearly visible. Modern technology allows you to take a 3D photo of the fetus.

Pregnancy 19 weeks. Fruit size

When the pregnancy of 19-20 weeks passes according to the relevant standards, the embryo already reaches a height of 20-22 centimeters. It's about the size of a banana. The baby's weight is240-300 grams. The baby grows all parts of the body.

As described in the norms of the ultrasound results, at the time when the pregnancy is 19 weeks, the size of the fetus has already increased significantly. The circumference of a small head is on average 160 mm, the length of the thigh is 30 mm, the length of the lower leg is 25 mm, and the length of the shoulder is 24 mm. Abdominal circumference approximately 140 mm. The length of the nasal bone is also very important, it measures about 8 mm. Fingers and toes grow. The foot is already formed. Its length reaches 2.5 mm, and from this stage, its size will remain that way until birth.

From the 20th week of pregnancy, the fetus begins to actively gain weight and grow. By the time of birth, the average weight of the baby is 3000 grams, and the height is 50 centimeters.

Fetal development

By the end of the fourth month after conception, the baby had not yet opened his eyes. However, he already distinguishes between light and darkness, he can turn to a strong light source. By this time, the baby knows how to move knives and handles, he begins to eat, roll over, constantly changes his position. In a few weeks, mom will be able to see how the heel, elbow or butt of her miracle protrudes on her stomach. The fetus is able to raise and turn its head, a grasping reflex is developed. His sleep is about 18 hours. During wakefulness, he learns the world around him. From now on, thumb sucking will be your favorite pastime. This is remarkable for the 19th week of pregnancy. An ultrasound photo can capture this amazing moment. Pregnancy 19-20 weeks is calm, but the expectant mother should be attentive to the state of her he althand limit physical activity.

It is very important that the mother's body has enough calcium and iron. For normal growth of the bones of the fetus, a pregnant woman should take vitamins prescribed by the gynecologist under whose supervision she is.

The role of the position of the fetus in the process of the upcoming birth

For a woman carrying a child, at 19 weeks of pregnancy, the location of the fetus becomes no less important than its growth and development. There are three options for the position of the baby in the womb.

At 19 weeks of gestation, the location of the fetus is not permanent. Since the size of the embryo is not yet large enough, it has enough space in the uterus in order to periodically change its position. Therefore, at this stage, the doctor will not worry.

At 19 weeks of gestation, the location of the fetus can be transverse, angular and pelvic. But before the birth of the child, there is a lot of time and the baby is able to roll over at any time and more than once.

Head presentation

The head is located towards the birth canal. This option is considered the most favorable, since the head is the largest part of the body of the developing embryo and the most difficult to get out during childbirth. After the head exits, the body easily leaves the womb. If the fetus has taken this position closer to birth, then this is a 90% successful birth.

breech presentation

In this case, in the process of childbirth, the pelvis comes out first, and then the whole body. Since, as mentioned above, the head isthe largest part of the baby's body, the birth process becomes more complicated. Very often, in pelvic diligence, the doctor decides on a caesarean section.

If at 19 weeks of pregnancy the location of the fetus is pelvic, then you should not worry too much. At the age of 17 weeks, the baby does not yet occupy the entire uterine cavity, and this gives him complete freedom in the possibility of changing his position.

Transverse presentation

In this situation, the head and butt of the fetus are located on the sides of the uterus. That is, it lies across relative to the birth canal. This case is the most difficult. Since with such a diagnosis, the process of natural childbirth is impossible. The baby is born only by caesarean section.

Until the pregnancy has reached 30 weeks, the expectant mother should not worry about how her child lies. At 19 weeks of gestation, the location of the fetus is unstable. And until the third trimester, no effort should be made to change the situation. The baby can take head diligence even a couple of weeks before delivery.

Recommendations for pregnant women

While carrying a child, a woman should take care of her he alth with special attention. The body of a lady in position needs constant replenishment with useful substances. Therefore, the diet must include cottage cheese, liver, meat, eggs, fish, fruits and vegetables. In no case should you smoke, drink alcohol and antibiotics. Every morning should start with a light warm-up.

To feel great, you should take daily walks in the fresh air, rest several times a day anddo what you love. Positive emotions and calmness play an important role. Throughout pregnancy, from the moment of registration, you should regularly visit a gynecologist and follow all the instructions. In case of any complications, you should immediately contact specialists for help.
