Menstruation will not be delayed after IUD removal, but there may be very few people who experience delayed menstruation. The delay of menstruation may be due to the following reasons: 1. 3-7 days after menstruation is clean is the best time to take the IUD, the endometrium may have some damage after taking the IUD, resulting in exfoliation and bleeding, and then the endometrium needs to be rejuvenated and repaired, so that the endometrium again exfoliates and bleeds, which means that the time of menstruation may be postponed. 2. 2 weeks after taking the IUD, sexual intercourse is prohibited, and premature intercourse without measures may lead to postponement of pregnancy. 3, mental tension, stress, environmental changes, endocrine disorders, heavy cold and other physical discomfort may also lead to delayed menstruation. If your period is delayed for 7-10 days, you can wait for your period again after ruling out pregnancy, without any deliberate treatment.
