When it expires or if you want to prepare for pregnancy, you need to remove the IUD first. In this case, women need to go to the hospital for an ultrasound examination to determine the location of the IUD and whether it is embedded or broken; then a vaginal discharge examination to determine whether there is any inflammation in the vagina; to make sure that there is no inflammation in the vagina, the IUD can be removed 3-7 days after menstruation. In addition, women should pay attention to the cleanliness of the vulva and vagina after removing the IUD. Avoid inflammation. Women can prepare for pregnancy one month after the IUD removal when the uterus has recovered well.
