Generally, prenatal check-ups are done at several months of pregnancy

Pregnant women all pay special attention to post-pregnancy check-ups, because post-pregnancy check-ups can ensure the health of the baby in their body and their own health. Therefore, many pregnant women want to fully understand how many months of pregnancy they should start prenatal check-ups. The following is a detailed introduction for many pregnant women, so you can have a further comprehensive understanding.

1. In early pregnancy (12 weeks of pregnancy), confirm intrauterine pregnancy and rule out abnormal pregnancy. Within 12 weeks of pregnancy, the fetus's organs are fully developed. A careful B-ultrasound examination can show whether there are any abnormalities in each important organ. Fetal malformations can be detected early, pregnancy can be terminated in time, and the impact on the expectant mother's body is relatively small. However, if there is a small amount of vaginal bleeding after pregnancy, or if there has been abdominal pain or a history of spontaneous abortion, etc., an ultrasound examination can clearly diagnose whether it is an intrauterine pregnancy and rule out ectopic pregnancy or hydatidiform mole.

2. At 18-20 weeks of pregnancy, check the gestational age and rule out fetal malformations. Pregnant women will begin to feel fetal movement at 16-18 weeks of pregnancy. Clinically, the wooden stethoscope should be able to clearly hear the fetal movement sounds on the pregnant woman's abdominal wall at 18-20 weeks of pregnancy. However, if the fetus is deformed, the fetal heart rate may still be normal. At this time, the doctor will recommend you to have an ultrasound examination. Because around 20 weeks of pregnancy, there is more amniotic fluid, the fetus is of moderate size, and has more room to move around in the uterus. At this time, B-ultrasound has better contrast, and can clearly see the various organs of the fetus. The fetus can be examined from the head, face to the limbs. If deformities or abnormalities are found, there is still time for further examinations such as amniocentesis, or to terminate the pregnancy in time.

3. During the 32-36 weeks of pregnancy, the main purpose is to understand the development of the fetus and rule out fetal malformations again. After 32-36 weeks of pregnancy, another B-ultrasound examination is performed to understand the development of the fetus, the position of the amniotic fluid and placenta, and to check again for any deformities. After 37-38 weeks of pregnancy, the position of the placenta and the amount of amniotic fluid should be understood. If the amniotic fluid decreases in the late pregnancy, multiple B-ultrasound examinations will be needed because the less amniotic fluid there is, the more likely the fetus will suffer from hypoxia and asphyxia during birth. Understand the function of the placenta in a timely manner and deal with any abnormalities promptly.

4. For those who give birth at the due date or more than 2 weeks after the due date, another B-ultrasound examination is required. The main purpose is to understand the maturity of the placenta and decide the mode of delivery, whether it is a natural birth or a caesarean section.

The above is a comprehensive introduction to how many months of pregnancy to start prenatal check-ups. For many pregnant women, it is important to have a comprehensive understanding of the above content, understand how many months of pregnancy to start prenatal check-ups, and then do prenatal check-ups at the correct time and through the correct prenatal check-ups, to ensure the health of the baby in your body and your own health.
