It is normal for pregnant women to dream of amniocentesis.

It is normal to do amniocentesis during pregnancy, indicating that the development of the fetus is normal. Down's screening can be arranged from 16 to 20 weeks after pregnancy. If Down's screening results are high-risk, amniocentesis can be arranged again. The accuracy of amniocentesis is higher, and it is low-risk and safe. Do a comprehensive examination on time during pregnancy, don't be too tired, and calculate the expected date of delivery. However, amniocentesis is risky, so you need to rest after the examination and be alert to the risk of premature delivery.
