How big is the belly when pregnant for three months

When a pregnant woman is three months pregnant, her abdomen will not be very big, and if the pregnant woman herself is relatively thin, it will be almost invisible. The abdomen will usually become visible only after four months of pregnancy.

In the case of three months of pregnancy, the fetus is about 2-9cm long and weighs about 9-23g. The baby's eyes, fingers and toes are clearly visible, his limbs can move freely in the amniotic fluid of the pregnant woman, and his upper and lower legs can alternate between extension and flexion. The baby will only be called a fetus when it enters the third month. At the beginning of the eighth week, the fetal head accounts for 1/2 of the total fetal length, and then the growth and development accelerates, and the body weight increases by 1 time by the twelfth week. At this time, the fetal internal organs have begun to function and can absorb the amniotic fluid and excrete it in urine. By the twelfth week, the shape of the fetus's private parts has been completed.

Physiological characteristics of pregnant women in the third trimester

During the third month of pregnancy, the pregnant woman's abdomen gradually bulges and the signs of pregnancy become more and more obvious. Let's take a look at the changes in the pregnant woman's body during the third month of pregnancy. The painful morning sickness gradually subsides, as the embryo replaces the male hormones. After two weeks or less, pregnant women will no longer feel nauseous at all. The breasts of pregnant women are rapidly expanding, and because the elastic fibers of the subcutaneous tissue of the abdomen and breasts are ruptured, dark red stretch marks appear in these locations. Some expectant mothers also experience stretch marks on their buttocks and waist.

What to check during pregnancy test

Some prenatal examination items need to be done every time during pregnancy, such as: measuring height, weight, blood pressure, etc. These examinations of the height and weight of the pregnant woman can be used to estimate whether the weight gain of the pregnant woman is normal. These examinations can also be used to assess the overall physical condition of the pregnant woman.

The prenatal check-up items in the third month of pregnancy include the fetal heartbeat test. By listening to the fetal heartbeat, it can be determined whether the fetus is alive or not. The normal fetal heartbeat of the fetus is 120-160 beats per minute. In addition, you can also use B-ultrasound to check the size of the fetus and calculate the expected date of delivery. These test results can be used as a reference for subsequent pregnancy tests.

In the third month of pregnancy, pregnant women also need to undergo a series of tests such as blood test, urine test, kidney function test, liver function test, etc., which can determine whether the pregnant woman has anemia, hepatitis, nephritis and other diseases that affect the health of the pregnant woman and the fetus. During the prenatal checkup, an electrocardiogram is also required to check whether the pregnant woman's heart function is intact.

During the third month of pregnancy, the pregnancy check-up should also be carried out for syphilis, hepatitis B six items, AIDS and other infectious diseases to ensure that the fetus can be born healthy.

What should you pay attention to during the third trimester of pregnancy?

The early stage of pregnancy, that is, the first three months of pregnancy, is a critical stage in the development of the embryo. At this time, because the test tube embryo is unstable, once an accident occurs, it is very easy to cause damage to the development of the embryo or even cause miscarriage.

In order to prevent this situation from happening, pregnant women should pay special attention to the following in the early stages of pregnancy:

1. Prevent sexual intercourse between husband and wife. Because the connection between the embryo and the pregnant mother's endometrium is not very close during early pregnancy, if the couple's sexual life is not good, it may cause uterine contractions and lead to miscarriage. Therefore, the third month of pregnancy preparation is a period when miscarriage is very likely to occur, especially for pregnant women who are at high risk of miscarriage.

2. Vaginal bleeding should be treated immediately. If you notice vaginal bleeding, even if it's only a small amount, you should see a doctor immediately, even if the bleeding seems to have stopped. This could be a symptom of some more serious problems. Therefore, it is necessary to see a doctor immediately to make sure that there are no problems with the pregnant woman and the fetus, and to eliminate the possibility of complications.

3. Pay close attention to the sleep of pregnant women. Sudden drowsiness: In the early stages of pregnancy, due to the increase in chorionic gonadotropin, the body becomes easily tired. In addition, the increased basic metabolism of pregnant women, changes in the endocrine system of pregnant women during pregnancy, rapid heat consumption in the body, and insufficient blood sugar levels are all reasons for always wanting to sleep. Therefore, once you feel tired, you need to take a nap as soon as possible.

What to eat during pregnancy

During the third trimester of pregnancy, the nutritional requirements for the mother are to have enough quantity and pay attention to the quality, especially to pay attention to the intake of foods rich in protein, carbohydrates, and various vitamins and minerals. After the 11th week of pregnancy, the fetus develops and grows rapidly, and the nutrients it needs are also increasing. From this stage onwards, not only the quality of food needs to be high, but the quantity also needs to be gradually increased. At this time, additional iron and calcium supplements can be taken under the guidance of a doctor.

The diet of pregnant mothers should still be light in taste and easy to digest. They should eat less greasy foods and choose their favorite foods as much as possible. To ensure the intake of protein, they can appropriately supplement more dairy products, eggs, beans, dried fruits, fish, and shellfish.

This time is the early stage of brain and bone growth of the fetus. You should pay attention to the intake of essential fatty acids, calcium, and phosphorus. You should also pay attention to the comprehensive intake of various vitamins, especially folic acid tablets. You can eat more fruits and vegetables (such as lettuce, wild rice, cabbage, cauliflower, rapeseed, etc.), legumes, dairy products, and make sure to eat appropriate amounts of fresh fruits every day.
