It is very harmful to have intercourse within two weeks of the abortion. You should not have intercourse within one month after the abortion. The uterine opening is open after the operation and the blood sinuses in the uterine cavity are not completely closed, so premature intercourse may bring bacteria to the vagina and cause endometritis by retrograde infection to the uterine cavity and even to the pelvis, which may affect future pregnancy. If the fallopian tubes are blocked or pelvic adhesions are caused, it may lead to infertility in the future. It is best not to have sex for one month after surgery. If you do have sex, it is best to take oral antibiotics for 3-5 days to prevent infection, pay attention to vulvar hygiene, change underwear and clean the vulva every day, and always remember to review the ultrasound and culture of secretions after menstruation.
