Ovulated 5 days ago and today OPK test show postive?

Hi everyone!

I took a clear blue pink test at midnight 5 days ago and it showed the smiley. I took a normal ovulation test the morning after that and it was negative. Today (possibly 5DPO) I took another ovulation test just for fun and it’s super positive. I took a pregnancy test (I know it’s super early) and it’s negative. I am a bit confused about the second ovulation test result. Also my period is due in 4 days and yes I ovulated SUPER late, just about 9 days before my period which usually fluctuate between 35/39 days. I have a pinching and burning sensation on the right side of my belly going up to my waist and down to my uterus. It’s like a pinch and something itchy. Alternating with cramps. What’s happening? I’m new to TTC please be nice to me 🥺❤️
