The IUD mainly serves as a long-term effective contraceptive method and is generally harmless to the body, so there is no need to worry too much. Only some women may experience discomfort with the IUD, because the IUD is a foreign body and can cause discomfort after it is placed, some women may experience menstrual disorders, and some may experience pain in the lumbosacral area.
