So according to the ultrasound I got done I don't have PCOS, but they didn't do blood work. Also my right ovary is 10ml and my left is only 3ml. They aren't worried about it and basically compared it to one breast being bigger than the other. I'm not sure what to do at this point because I know something is wrong. I've always had irregular periods, but they have been getting worse. Last month I was 21 days late and this month I am 11 days late. I have also always been overweight and no matter what I do I can't seem to get it off. There is a possibility that it could be Endometriosis, but my doctor doesn't want to do a lap because of my weight.
