Ovary pain during pregnancy is relatively uncommon. It can occur due to a variety of causes, including ovarian cysts, ectopic pregnancy, or ovarian torsion. If you experience any pain in your ovaries during pregnancy, it is important to contact your healthcare provider right away. Ovary pains during pregnancy can be treated with rest, over-the-counter pain relievers such as ibuprofen or acetaminophen, and warm compresses.
