During the preparation period, not only women should prepare for pregnancy, but also men should pay attention to quit smoking and drinking, exercise and strengthen their body, maintain good hygiene habits, and increase nutrition appropriately to improve the quality of eggs and sperm, so as to ensure the healthy and normal growth and development of the fetus after pregnancy, and in the first three months of pregnancy, women need to take small doses of folic acid to prevent fetal malformations. In the first 3 months of pregnancy, women need to take a small dose of folic acid to prevent fetal malformations. From the point of view of eugenics, it is best for women to get pregnant 3-6 months before pregnancy, and both men and women need to adjust their bodies, and also do a full body physical examination to facilitate the development of the fetus after pregnancy.
