Ovulation pain but OPK fading

Bellawella123

Hi ladies! Thoughts pls! So my opk tests have been getting gradually darker, darkest line was before bed last night. Today is cycle day 13, flow suggests I ovulate tomorrow.

I’ve been having crampy twinges in left ovary which feels like ovulation twinge. Yet opk is getting fainter. I’d have thought it would have been positive today given the cramping. Or do you cramp AFTER the egg is released? Confused.com

Any thoughts gratefully received :) xxx
