Four months pregnant boy girl belly shape

In fact, during pregnancy, you will find that the shape of your belly becomes larger and larger with the years, and there will be some slight changes. It is impossible to determine the gender.

Anemia often occurs during pregnancy, and this anemia is mainly iron deficiency anemia.

During pregnancy, due to the growth of the fetus, the demand for oxygen increases, so breathing is slightly faster than normal; the respiratory mucosa becomes congested and local resistance is poor, which can easily cause upper respiratory tract infections.

Nausea, vomiting, abnormal taste, changes in appetite, etc. may occur in early pregnancy and usually disappear gradually after 12 weeks of pregnancy. This is related to the fact that the placenta secretes more progesterone, which affects gastrointestinal function.

After a woman becomes pregnant, in order to adapt to the needs of fetal growth and development, various systems in the body undergo a series of changes under the influence of various hormones secreted by the placenta, among which the reproductive system undergoes the greatest changes.

The uterus is where the fetus grows and develops, and the changes in the uterus are most obvious after pregnancy. For example, the uterine blood vessels become thicker, increasing the blood supply to the placenta to ensure adequate nutrition for the fetus. The volume of the uterus increases significantly. By the time the fetus is full-term, the uterine capacity is about 1,000 times greater than before pregnancy. The secretion of cervical mucus increases and gathers in the cervical canal to form a "mucus plug" to prevent bacteria from entering the uterine cavity and prevent infection.
