It is normal to have intercourse only after 2 weeks after IUD placement, because most people will have a small amount of vaginal bleeding when the IUD is first placed, this bleeding will last 3-5 days and will be clean. Some people may experience irregular vaginal bleeding or pain in the lower abdomen within 3 months after IUD placement. If irregular vaginal bleeding or excessive menstruation still occurs after 3 months, the ring may not be suitable for you and you need to remove it.
