In the early stage of pregnancy, because the development of the embryo is not stable, the placenta is not formed, the connection between the fetus and the uterine wall is not too firm, the stimulation of intercourse or other external factors may easily cause miscarriage, and intercourse is prohibited in the early stage of pregnancy. It is advisable to pay attention to rest, preferably in bed, and observe whether there is vaginal bleeding. If a small amount of bleeding occurs, it is best to go to the hospital in time and under the guidance of the doctor for fetal preservation treatment. It is recommended to pay attention to folic acid supplementation in early pregnancy to prevent neural tube malformation of the fetus, pay attention to a reasonable diet, do not eat spicy, cold and stimulating food to avoid abdominal pain or diarrhea, and pay attention to regular pregnancy tests.
