Doctor's answer:

After artificial abortion, it is even more important to maintain cleanliness and hygiene of the external genitalia. Wash with warm water 1-2 times a day and change menstrual pads and toilet paper frequently. Do not take a bath for 2 weeks or until vaginal bleeding stops. Avoid sexual activity for 1 month to prevent infection of the reproductive organs. If you have fever, abdominal pain, or abnormal odor in vaginal discharge, it may be caused by infection and you should seek medical attention promptly.
During artificial abortion, after the placenta is detached, small amounts of bleeding may occur on the wound left on the uterine wall. This condition usually gradually stops within 3-5 days of vaginal bleeding as the uterus contracts and the wound heals, but it should not exceed 10-15 days. If the amount of vaginal bleeding exceeds the menstrual flow or the duration is too long, you should seek medical attention promptly.
