Patient's question:
Pregnant in the early stages took allergy medicine, now pregnant 20-21 weeks,Doctor's answer:
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 if the pregnant woman suffers from a certain disease that cannot adapt to the changes of pregnancy, pathological conditions can arise in both the pregnant woman and the fetus. Through prenatal examinations, complications (such as pre-existing diseases in the pregnant woman, such as heart disease) and complications (such as diseases that occur during pregnancy, such as preeclampsia) can be detected and prevented early, abnormal fetal positions can be corrected in a timely manner, and fetal abnormalities can be identified, determining the mode of delivery.
