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 prenatal checkups are needed in the third month of pregnancy? Obstetricians explain in detail: For most normal pregnant women, after the first checkup (initial checkup during pregnancy), they should be checked once every 4 weeks, once every 2 weeks after 28 weeks, and once a week after 36 weeks until the pregnant woman gives birth.
