Agree. I could pretty much always tell when I was ovulating because of the pain. Sometimes I could barely get out of my car, my left leg hurt so much. My gyn also diagnosed endometriosis one time when I was in so much pain one month, I could barely stand. But she just said, wait and see if it happens again. It didn't. I was about the same age. She said it took just a tiny dot of misplaced tissue on a nerve to cause that much pain.
