Waiting for the birth of a new life is an exciting period in the life of every woman. But any future mother is worried about how pregnancy should go and how the baby should develop in her stomach. In this article, I will discuss 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 woman’s body. But already in the second trimester (from 13-14 weeks), the condition becomes more stable. Most often, morning sickness and dizziness pass. Pregnancy of 18-19 weeks is more calm, the fetus has already taken root in the mother's body and continues to actively develop. However, you should be responsible for your situation, avoiding stress, physical exertion and injury. There is a slight risk of premature birth at this time.
How to calculate the gestational age and date of birth
Most women who first learned about their situation, begin to calculate the term and date of birth. But you should be aware that there is an obstetric gestation period, according to which the pregnancy lasts not nine months, but 41 weeks, that is, more than nine. A gynecologist begins a pregnancy countdown from the start date of the last menstrual cycle. Usually the difference between the obstetric period and the mummy’s calculations is about two weeks. Following these rules, it is easy enough to find out the approximate day the baby is born.
19 weeks of pregnancy, how many months are left before the birth according to the obstetric calendar? After calculations, it turns out that this is the end of the fifth month, therefore, four more are left before delivery. 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 should correspond to 17 weeks of development.
Pregnancy is 18-19 weeks. Features of a growing abdomen
Before the beginning of the second period of fetal development, the abdomen is almost invisible, since the baby is still very small and the uterus has only slightly increased in size. The abdomen at the 19th week of pregnancy is already becoming significantly larger, which limits the future 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 press on the internal organs of the pregnant woman. Very often heartburn, constipation and urge to urinate become more frequent. Much attention should be paid to the food consumed, since from that moment the doctor begins to strictly monitor the weight of the woman carrying the baby. It is important to be responsive to your sleeping position. It is undesirable to sleep on the stomach or back, because this can harm the fetus. In the “supine” position , there is a risk of damage to the fetus, and in the “supine” position there is a high probability of crushing the aorta through which oxygen enters. You should rest lying on the side where the baby is.
At each medical examination, starting from the second trimester, 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 the bearing of a child has its own individual characteristics, depending on her physique and body weight before pregnancy. But there are certain permissible norms.
The abdomen at the 19th week of pregnancy, when measured vertically, reaches 18-20 cm. The uterus is already starting to rise to the navel. These data are provided only for a single pregnancy.
If the doctor notes abnormalities, then the pregnant woman is sent for additional examinations. Since the cause of an increase in the abdomen can be too much amniotic fluid or other deviations.
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 already behind, the 19th week of pregnancy has come. What happens to the baby’s body at this point?
Within five months, the fetus developed from an embryo to a little man. At this time, the baby has already formed hands, legs, fingers, auricles, the shape of the head and parts of the face. The respiratory, digestive and nervous systems, subcutaneous layer, and tooth rudiments also continue to form.
If before this time mommy already felt the first movements of her child, now his movements will become more confident and clear. And some expectant mothers only have to rejoice at the first shocks and kicks. The brain of the child is already actively developing. The embryo begins to move in the stomach, very often changes its position. In connection with the onset of brain activity, fetal movements become more concentrated. Perhaps a reaction to the sounds of the voice of the parents and the touch of the hands on the stomach.
Second fetal ultrasound examination
As a rule, in the second trimester of pregnancy, in addition to all the usual examinations, an ultrasound examination of the fetus is also performed.
At the first planned study, the doctor confirms the presence of a normal pregnancy (not intrauterine or frozen), clarifies its duration, determines the age of the fetus and sex of the baby (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 embryo and to examine its anatomical development. This study also determines the position of the fetus in the womb, which plays a large role in the manner in which delivery will take place. Also, with the help of the apparatus, the doctor performs fetometry, that is, determines the size of the circumference of the head and abdomen, seeds of the arms, legs, hips, shoulders. The symmetry of the external and internal organs is visible. The determined sex of the child has a probability of up to 90%.
Based on the data recorded by a specialist, it is concluded that the development of the fetus corresponds to its embryonic age. In addition to studying development 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 of indications of ultrasound.
• 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;
• DG - from 23 mm to 31 mm;
• DP - from 20 mm to 26 mm;
• coolant - from 125 mm to 155 mm;
• Tax Code - from 5.2 mm to 8.0 mm;
• growth - 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 image already shows the formed man, all parts of the body are clearly visible. Modern technology allows you to make a 3D photo of the fetus.
Pregnancy 19 weeks. Fetal size
When a pregnancy of 19-20 weeks passes according to relevant standards, the embryo already reaches a height of 20-22 centimeters. This is about the size of a banana. The weight of the crumbs is 240-300 grams. The baby grows all parts of the body.
As described in the norms of ultrasound results, during the period 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, the length of the shoulder is 24 mm. The circumference of the tummy is approximately 140 mm. The length of the nasal bone is also very important, it has dimensions of about 8 mm. Fingers of pens and legs grow. Already formed foot. Its length reaches 2.5 mm, and from this stage its size will remain so 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 growth is 50 centimeters.
Fetal development
By the end of the fourth month after conception, the baby has not yet opened his eyes. However, he already distinguishes between light and darkness, can turn to a strong source of light. By this time, the baby knows how to move knives and handles, he begins to eat, turn over, constantly changing 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 lift and rotate the head, a grasping reflex is developed . His sleep is about 18 hours. During wakefulness, he learns the world around him. From this moment on, your finger will be your favorite pastime. This is a wonderful 19 week of pregnancy. A photo taken on an ultrasound scan can capture this amazing moment. Pregnancy of 19-20 weeks is calm, but the expectant mother should be careful about her health and limit physical activity.
It is very important that the mother has enough calcium and iron. For normal growth of the bones of a pregnant fetus, vitamins prescribed by a gynecologist, under whose supervision she is, should be used.
The role of the fetus in the process of forthcoming birth
For a woman carrying a child, at 19 weeks of gestation, 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 fetus is not permanent. Since the size of the embryo is still not 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 fetus can be transverse, angular, and pelvic. But before the birth of a 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 comes out most difficult during childbirth. After the exit of the head, the body easily leaves the womb. If the fetus has taken such a position closer to birth, then this is 90% of successful births.
Pelvic presentation
In this case, in the process of childbirth, the pelvis first comes out, and then the whole body. Since, as mentioned above, the head is the largest part of the baby’s body, the process of birth is complicated. Very often with pelvic diligence, the doctor decides on a cesarean section.
If the location of the fetus is pelvic at 19 weeks of pregnancy, then you should not worry much. At the age of 17 weeks, the child does not yet occupy the entire uterine cavity, and this gives him complete freedom in the possibility of changing his position.
Cross 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 this diagnosis, the process of natural birth is impossible. The baby is born only with the help of a caesarean section.
Until the pregnancy reaches 30 weeks, the expectant mother should not worry about how her child lies. At 19 weeks of gestation, the fetus is unstable. And until the third trimester, no efforts should be made to change the situation. A baby can take head diligence even a couple of weeks before giving birth.
Pregnant recommendations
During the bearing of a child, a woman should treat her health with special attention. The body of a lady in a position needs constant replenishment with useful substances. Therefore, the diet must have cottage cheese, liver, meat, eggs, fish, fruits and vegetables. In no case should you smoke, drink alcohol and antibiotics. Every morning you should start with a light workout.
For good health, you should take daily walks in the fresh air, relax several times a day and do what you love. An important role is played by positive emotions and calm. Throughout pregnancy, from the moment of registration, you should regularly visit a gynecologist and follow all instructions. In case of any complications, you should immediately contact specialists for help.
