The bleeding usually does not exceed 1 week after the IUD is placed. After the IUD, since the IUD is a foreign body to the body, this foreign body stimulation may cause bleeding from the endometrium, and the bleeding will disappear when the body adapts to this stimulation. After the IUD, it is normal to have a small amount of bleeding or no bleeding within 1 week after the procedure. After the operation, you should take rest, pay attention to prevent infection, and do not have sex for half a month. If the bleeding after IUI lasts for a long time and is still not clean for more than 1 week, you need to go to the hospital, take hemostatic drugs under the guidance of the doctor and pay attention to the hygiene of the perineum to prevent infection. After IUI, you should also pay attention to check the position of the ring regularly to prevent the ring from moving down.
