If you are not in your third trimester now, you can continue taking folic acid. If you are already more than three months pregnant, there is no need to continue taking folic acid. Folic acid is used to prevent fetal malformations. If you start taking folic acid when preparing for pregnancy and take it until the third trimester, the rate of fetal malformations after birth can be reduced. It is not necessary to take enough folic acid to prevent fetal malformation, it is just a preventive medicine. After pregnancy, eat more fresh fruits and vegetables, which can play the role of vitamin supplementation, and eat moderate amount of high quality protein-rich food to improve the body’s immunity. In the middle and later stages of pregnancy, you can take calcium supplements in moderation, which can play a role in enhancing the growth of the baby and strengthening the baby’s constitution.
