If the position of the IUD is not normal, the following reactions may occur: the first is irregular vaginal bleeding, which may occur during menstruation and prolong the duration of menstruation. The second is recurrent lower abdominal pain, accompanied by a small amount of vaginal bleeding. If either of these situations occurs, it indicates that the position of the IUD has shifted. In addition, if menopause occurs after the implantation of the IUD, it may be due to the abnormal position of the IUD, which can not achieve the contraceptive effect of pregnancy, so there will be a history of menopause, and it is recommended to take an early early pregnancy test to find out if you are pregnant.
