Preconception physical examination is an important step for couples to prepare for pregnancy. It can help identify and solve problems that may affect pregnancy and fetal health. Women should take a pregnancy test within two weeks after their menstrual period, avoid sexual intercourse and clean the vagina; men need to avoid sexual intercourse 3-5 days before the pregnancy test, and pay attention to diet and rest. Both husband and wife should pay attention to maintaining good living habits, such as quitting smoking, limiting alcohol, and maintaining a regular schedule. Also, keep the pregnancy test report for reference when needed.
