Ovulation cramp question.

I hardly every actually cramp during ovulation maybe a small handful of times. Of course my and my husband have had sex every night this week and confirmed ovulation with tests. I've noticed that the tests stayed positive for 3-4 days like
Blatantly positive!!! And I cramped last night before and after sex (I was a trooper) on both sides. I cramped throughout my Lowe abdominal from one hip bone to the other!!
What could this mean????
