After the IUD is placed, if there is only occasional bleeding during ovulation and the menstrual period clears normally, you can consider temporary observation to see if the bleeding will continue during the next ovulation period, because occasional ovulatory bleeding may not be caused by the IUD, but is a physiological manifestation caused by the fluctuation of estrogen. If ovulatory bleeding occurs for three consecutive months after the IUD, you need to check the sex hormone panel to see if there is any abnormality in the endocrine function of the ovaries, and also check the ultrasound to see the exact location of the IUD. If there is no abnormality in the sex hormone panel and the IUD has moved down slightly, you can only consider surgery to remove the IUD as soon as possible. If the ultrasound indicates that there is no abnormality in the IUD but there is a slight abnormality in the sex hormone panel, you can consider taking combined estrogen and progestin preparations to regulate ovulatory bleeding by suppressing ovulation.
