It is not allowed to have intercourse before having an abortion. If the patient has intercourse before the abortion, especially within 48 hours before the abortion, the man may bring pathogenic bacteria into the woman’s body, and then the abortion may bring pathogens into the woman’s pelvis, causing pelvic inflammatory disease and pelvic infection. If the vaginal discharge test indicates vaginal inflammation, abortion should not be performed until the vaginal inflammation is cured. Before having an abortion, the patient’s body should be evaluated to see if it can tolerate the procedure. If it cannot tolerate the procedure and if there are contraindications to abortion, abortion is also not allowed. Before having an abortion, a gynecological ultrasound is needed to clarify early intrauterine pregnancy before performing an abortion.
