Pelvic pain

Artie
I am seeing a doctor Weds, but I thought I'd ask for opinions. Saturday wouuld have been my ovulation day. I had some pretty bad pain that day that kept me in bed all day. It eased up sunday but came back full force sunday night. It hurts so much it makes me feel nauseated. Im 31, have 2 kids ages 7 and 3 and am not TTC. I had long heavy, super irregular periods before kids but regular, 3-5 day ones after. Ovulation HURTS and occasionally it hurts for many days after, like this time. Does anyone have any thoughts on this or as similar experiences?
