Pelvic pain

I've had pelvic pain since I ovulated a week ago. It's constant and really bothering me. I've had a diagnostic laproacopic surgery last March to see if I have cysts, fibroids, or pcos but everything came back normal. He said my uterus was a bit on the larger side. I'm so tired of this pain. On my days off from work I try to just lay in bed with a heating pad. Anyone else experienced this?
