It is most suitable to remove the IUD 3~7 days after menstruation, and usually the pain can be tolerated without anesthesia injection. In 3~7 days after menstruation, the lining of the uterus is still relatively thin, the damage to the lining of the uterus is slight, the bleeding time is short, and there is still enough time for the lining of the uterus to recover after the removal of the IUD, which will not affect the next menstruation, so this is a more suitable time for the removal of the IUD. It is recommended that women should pay attention to vulvar hygiene after IUD removal to avoid infection, take a rest for 1~3 days, and prohibit sexual intercourse, tub bath, swimming, etc. for 2 weeks, and avoid laborious and heavy physical work after IUD removal. If vaginal bleeding, abdominal pain, leukorrhea and other abnormalities occur, it is recommended to consult a doctor in a timely manner, under the guidance of the doctor, improve the relevant examination, to clarify the cause of the disease, symptomatic treatment.
