After removing the IUD, menstruation usually returns to normal in the same month, and in some cases, menstruation returns to normal within three months. The time for IUD removal is usually within three to seven days after menstruation. Under normal circumstances, after IUD removal, menstruation will usually come normally at the time of the next menstrual period, and menstruation that is not more than seven days ahead of or behind the normal time is considered normal. If your period is delayed for more than seven days and you have had sex, you should first go to the hospital and have your blood tested for HCG to determine if you are pregnant. After ruling out pregnancy, you need to regulate menstruation. After removing the IUD, the uterine lining is traumatized, and the uterine environment changes, which may lead to irregular menstruation, which needs to be observed for three months, and usually returns to normal in three months or so. After removing the IUD, if the menstruation is more than seven days ahead or behind schedule, you need to consult the doctor in time and adjust the menstrual cycle under the doctor’s guidance, and do not use your own medication to avoid adverse consequences.
