Cramps in my left ovary?

So I have PCOS & I have irregular cycles. But I usually don’t have sharp cramps in my ovaries. It’s usually like menstrual cramps in the center of my uterus not focused on one side. Glow says I’m ovulating but I don’t have that much CM. My last period was Oct. 30th thru Sept. 5th. I’ve been taking Folic Acid because my boyfriend & I have been TTC for nearly 3 years. About a day & through last week after my period, we obviously had unprotected sex & one of those days I notice that I did have a lot of CM. So I’m confused as to what the cramps could be.
