Ovulation question

Leslie • 💙•SAHM• Boy mom•pcos•breastfeeding•💙

I’m on CD19 my temp shows ovulation but I have yet to get a positive OPK. I wasn’t testing regularly but how possible it is that I missed it for just not testing one day??

FF says I ovulated on cd10 which I didn’t test that day.

I do have pcos and I’m breastfeeding as well.
