Couples preparing to get pregnant have the following taboos before getting pregnant: within six months before getting pregnant, men should completely stop smoking, abstain from alcohol, and try not to take drugs at the same time. Women should also try not to drink alcohol, do not inhale second-hand smoke, do not stay up late, and refrain from getting angry, quarreling, and so on. Keeping a happy mood before pregnancy is essential to promote a normal pregnancy and the normal development of the embryo. Also before getting pregnant, both husband and wife should insist on exercising every day to keep their health at an optimal level. Both men and women should undergo eugenic screening before pregnancy and if any illnesses are found, they should be treated aggressively. Women should start taking folic acid supplements 3 months before they are ready to get pregnant, and at the same time, they should pay attention to dietary diversity and nutritional enhancement to prepare for pregnancy.
