Weird Pain 😥

Haya

My fertile window starts this Saturday and ends next Friday but my opks indicate I'm still pretty far from ovulation. This evening, while watching tv, my thigs, lower back and pelvic area started hurting. It feels like the kind of pain you get before your period, on top of that, my right ovary is slightly crampy, it sent a shot of pain up my abdomen too. I'm really not sure what's happening. Any guesses or suggestions?
