When is the time for ultrasound examination during pregnancy?

During the ten months of pregnancy, women should not have physical examinations too frequently. Many women have physical examinations several times a month. This practice has a great impact on the growth of the fetus, and frequent examinations can also be harmful to their own bodies. Women should also pay attention to this. So when is the best time for ultrasound examinations during pregnancy? The following is a detailed introduction so that you can have some understanding.

Ultrasound examination time during pregnancy:

During pregnancy, expectant mothers will generally undergo 3-4 ultrasound examinations. Under normal circumstances, the best time to undergo an ultrasound examination is during the 20th to 24th week of pregnancy, which is the most important color ultrasound for screening for fetal anomalies. Most possible problems with the fetus can be identified during this period. It can see the fetal body, head, fetal heartbeat, placenta, wool and umbilical cord, etc. It can find out whether the fetus is alive, whether it is a multiple birth, and even determine whether the fetus is deformed.

1st ultrasound: 12-16 weeks of pregnancy

It can determine whether the pregnancy is single or multiple, and can measure the size of the fetus and its development. Often used to determine the gestational age of the fetus in early pregnancy.

Second ultrasound: 20-24 weeks of pregnancy

At this time, you can understand the development of the fetus, whether there are any surface deformities, and further understand the fetal position and amniotic fluid volume.

The third ultrasound: 37-40 weeks of pregnancy

The B-ultrasound at this stage can help expectant mothers observe the fetal position, fetal size, degree of placental maturity, whether the umbilical cord is wrapped around the neck, etc., conduct a final assessment before delivery, and make various preparations before delivery, so this B-ultrasound is very important.

After understanding the time for ultrasound examinations during pregnancy, women can choose to have ultrasound examinations according to the above time. However, women should pay attention to each examination. If they feel uncomfortable, they should report it immediately to avoid affecting the fetus. Physical examinations should be conducted in large hospitals.
