During pregnancy, it is recommended that pregnant women take folic acid tablets in the first trimester as prescribed by the doctor, as folic acid can prevent neural tube abnormalities in the fetus, and pregnant women should not do vigorous exercise during pregnancy, maintain a good mood, eat a diet high in protein and vitamin-rich foods, and make sure to do a good job of pregnancy checkups, and make decisions on a case-by-case basis if abnormalities are found in the checkups.
