After the gynecological examination, if possible, you should wait 1 week before having intercourse, because during the examination, the vagina is opened with a speculum, which may touch the cervix, including the blood vessels of the vaginal wall, and there may be a small amount of bleeding, which will take 3-5 days to recover. If you have intercourse too early, it will stimulate the development of continuous bleeding, resulting in increased bleeding and even abnormal bleeding due to mucosal inflammation or edema. Before and after intercourse, you should wash both genitals as much as possible to avoid the chance of cross-infection. If you do not intend to have children, you should take condoms for contraception as much as possible to avoid unwanted pregnancies, and if you have a medical abortion or an abortion, there will be great damage to the uterus as well.
