What could cause extreme ovarian pain with a IUD?

Extreme ovarian pain with an IUD could be caused by several factors, including ovarian cysts, pelvic inflammatory disease, or a misplaced IUD that irritates surrounding tissues. In some cases, the IUD may cause hormonal imbalances leading to painful ovulation or menstrual cramps. Additionally, an infection or inflammation in the pelvic area could exacerbate discomfort. It's important to consult a healthcare provider for an accurate diagnosis and appropriate management.
