Hormones Imbalance??

Ka

I started to break out around my jaw line and this hasn’t happened to me in a long while. I’m 29 and I don’t know if it’s a possibility I have PCOS, I had a miscarriage about 6 months ago (Blighted Ovum). The dr did ultrasounds of my ovaries during this time frame and found I had a corpus luteum on my right ovarie. How do drs diagnose PCOS? Would they have been able to tell from one of those ultrasounds?? It’s freaking me out because I want children and have been trying now for about a year. 😔
