I had a blazing positive opk on Sunday Sept 8th so it appears I ovulated yesterday Monday Sept 9th. This morning (10th) when I woke up I started having really bad period-like cramps that radiated to my ass whenever I would move around. It would stop me in my tracks. This would usually happen to me just before my period or while I’m on it. For it to be happening so soon is perplexing me. My ovulation symptoms typically consist of ovary aching on one side or the other, lower back aches, and feeling heavy in my uterus area so I don’t believe the heavy cramping has anything to do with ovulation. Has anyone experienced this type of cramping shortly after ovulating and gotten their bfp?
