You should not have sex a week before the abortion, even with a condom. Even if you wear a condom, it is impossible to prevent the pathogenic bacteria from entering the vagina, which may cause inflammation of the cervix, endometrial inflammation or pelvic inflammation. Especially after the abortion, the resistance is reduced, which is more likely to lead to pathogenic bacteria infection, so before the abortion, even if you wear a condom, you should not have intercourse. In addition, vaginal pills or vaginal douching should not be used before an abortion, especially within 24 hours before the abortion.
