Pain during period

Jessica • Married to my soulmate. I have 2 angel babies. TTC my rainbow baby
I was diagnosed with PCOS in February. I have always had cramps during my period but this month I only have pain in my left side in the region where my ovary is. I had a miscarriage at 10 weeks in May with several complications and the pain then was nowhere near as bad as the pain now. I'm not late or anything my cycle has always been regular so I'm really confused as to what it may be! Anybody have any ideas? Thought I would post in here whilst waiting for my doctor to ring me back xx
