When the IUD falls out, it does not necessarily cause bleeding clinically. For example, if the uterine orifice is relatively loose, the IUD coming out will not cause damage to the mucosal tissue, so there will be no bleeding. Often, clinically, the patient does not find that the IUD has fallen out, and only when the IUD is checked does she find that the IUD is missing. Therefore, women who have an IUD are recommended to have their IUD checked at least once a year, mainly to find out if the IUD has shifted or if there is any dislodgement. If the IUD is displaced, it will not work clinically, so it should be removed and replaced with a new IUD in a timely manner. In addition, after the IUD, some women may not adapt to it, so it is recommended to observe it for three months and to treat it with medication. For example, if there is irregular vaginal bleeding after the IUD, after giving symptomatic treatment, if you still can’t adapt to it after three months, the IUD should be removed.
