Doctor's answer:

Hello, yes, prenatal examination---clinical examinations performed on pregnant women and fetuses during pregnancy. Due to the growth and development of the fetus, a series of adaptive changes occur in the various systems of the pregnant woman's body. If these changes exceed the physiological range or the pregnant woman herself suffers from a disease that cannot adapt to the changes of pregnancy, pathological conditions can occur in both the pregnant woman and the fetus. Generally, doctors will advise women with risk signs of prenatal examination to pay attention to keeping warm and avoid coldness. Additionally, patients should also pay attention to having a comfortable environment, which is beneficial for rest. Wishing the patient a healthy delivery.
