PCOS question

I've been really worried lately since starting my period. I have PCOS and went off my medication for 3 months because my doctor wouldn't renew my prescription. Finally, I got my meds and started my period again, but I've been feeling pain in my mid lower abdominal area. It feels like it's where my uterus is. I've never felt pain in that specific area before and it's worrying me. I'm not sure if it's because of my period, if it's because I haven't been having regular periods every month, cysts (I've never had cysts that I know of), or something else. I just don't want to be stressing out over nothing.
