There will be two kinds of distinctions for miscarriage, one is painless abortion and the other is induction of labor. For painless abortion, if you want to have an IUD, you need 3-5 days after having 1 menstrual period, no intercourse and no vaginal washing. Before the IUD is performed, an ultrasound must be done to make sure that the shape of the uterine cavity is normal. If it is normal, the IUD can be performed, but if the uterus does not recover particularly well and the uterine cavity is large, it is recommended to wait for one more month before performing the IUD. At the same time, you need to perform IUD after induction of labor, because induction of labor is similar to giving birth once, the recovery of the uterus needs a process, as far as possible, after 3 months of review, the uterine form returns to normal, then you can perform IUD. Avoid the chance of uterine perforation due to premature IUD, so this is the time to pay attention.
