The best time to remove the IUD is usually 3-7 days after menstruation, depending on the actual situation of the individual, the time should be chosen under the guidance of the doctor. Usually, the best time to remove the IUD is 3-7 days after menstruation and no sexual intercourse during this period, and at the same time, genital inflammatory diseases and other contraindications should be ruled out; the IUD needs to be taken out in time when it is dislocated, resulting in persistent bleeding from the vagina, or when the IUD is embedded in the uterine myometrium, or even penetrates through the myometrium and is free in the abdominal cavity. Peri-menopausal women who have not had menstruation for half a year and have confirmed that they are not pregnant should have the IUD removed as soon as possible to avoid vaginal, cervical and uterine atrophy, which may make the procedure difficult. Removal of the IUD needs to be done in a hospital by a professional doctor to avoid any adverse situation.
