At 4 months of pregnancy, the fetus is about 16 centimeters long and weighs about 120 grams. At this time, the fetus\’s internal organs and other organs are getting closer to the completion stage, fully possessing the appearance of a human being, and men and women can be distinguished from the genitals. The fetal hair begins to grow, the bones and muscles gradually develop, the hands and feet can do slight activities, the heartbeat is active, and the heart sound can be measured with an ultrasonic stethoscope.
By the time I was 4 months pregnant, the painful morning sickness had passed. Pregnant women will feel more comfortable and their appetite will begin to increase at this time. Frequent urination and constipation gradually returned to normal, but secretions remained unabated.
At the end of 4 months, the placenta has been completed, the possibility of miscarriage is greatly reduced, and it can be regarded as entering a stable period.
At this time, the uterus is as big as a child\’s head, and you can roughly see a \”big belly\” from the outside.
Below, Bell Parenting Network will give you a detailed introduction to the physical changes of expectant mothers in the 4th month of pregnancy:
4th month of pregnancy 1st week (13th week of pregnancy)
In the 13th week of pregnancy, I have entered the second trimester. The expectant mother\’s belly begins to swell, her original clothes begin to become inappropriate, and soon she will need to wear maternity clothes. Of course, from the outside, she looks more like a beautiful pregnant mother.
At this time, expectant mothers had better focus on what they must do in the future for a smooth delivery and postpartum recovery – exercise. For example, you can do some pregnancy and childbirth exercises purposefully, and ask your husband to take a walk with you after dinner every day. This is the safest and healthiest sport. In addition, some pregnant women can express milk from their nipples, which looks like colostrum secreted just after giving birth.
4th month of pregnancy, 2nd week (14th week of pregnancy)
Now expectant mothers have significantly increased leucorrhea. It is a secretion from the vagina and cervix that contains lactobacilli, vaginal exfoliated epithelial cells, and white blood cells. This is due to high estrogen levels in the body, and pelvic and vaginal congestion leading to increased vaginal secretions, which is normal.
Expectant mothers will gain weight this week, the size and shape of their breasts will change, and their figure may not be as good as before. Occasionally itchy skin may occur, but there will be no lumps or lesions. As the uterus enlarges, the abdomen continues to bulge and weight increases. The expectant mother begins to feel plump, her breasts gradually become larger, the area of the areola also becomes larger, the color becomes darker, and some small spots will appear around the nipples. In addition, some pregnant mothers can express milk from their nipples, which looks like colostrum secreted just after giving birth.
3rd week of 4th month of pregnancy (15th week of pregnancy)
In the 15th week of pregnancy, you can tell you are pregnant just by looking at your belly, and the size of your clothes will change accordingly. Expectant mothers can feel their uterus at a position of 7.610 cm below the belly button. The expectant mother\’s body curves have changed and her weight has increased month by month. The original clothes and pants are almost no longerI can wear it again, and my daily life can basically return to its original state.
At this time, endocrine changes in some pregnant women cause the skin pigmentation on the face and body to darken, pigment spots appear, hair increases, acne-like dermatitis occurs, the face loses its luster, and edema occurs. With the development of the fetus, the load on the cardiopulmonary function of pregnant women increases, the heart rate accelerates, and the breathing accelerates and deepens, which may aggravate the original anxiety.
The expectant mother can now clearly feel fetal movement. If you have time, record the time of your baby\’s first fetal movement as a witness to future memories. For pregnant women who have had a history of pregnancy in the past, expectant mothers may find that the fetal movement occurs earlier than before. This is normal and nothing to worry about.
4th month of pregnancy, 4th week (16th week of pregnancy)
This is the happiest stage of pregnancy, when you feel energetic, energetic and easily excited. The physical sensations are: energetic, swollen breasts, increased appetite, and prone to indigestion and constipation due to weakened digestive system function.
At 16 weeks of pregnancy, due to excessive secretion of estrogen during pregnancy, the expectant mother will cause the melanocytes on the skin surface to secrete a large amount of pigment, making the skin darken. It often occurs in darker areas such as freckles and birthmarks. This is a pregnancy spot, don’t worry, it will disappear on its own after delivery.
