Pelvic pain can have several possible causes, including menstrual cramps, ovulation, endometriosis, ovarian cysts, fibroids, pelvic infections, urinary conditions or gastrointestinal problems. The location, severity, duration and timing of the pain can help determine its cause. Persistent, recurring or severe pelvic pain should be medically evaluated, especially when accompanied by bleeding, fever, vomiting or other concerning symptoms.
