Hi MadeWithLove, doctors can sometimes use different criteria for the diagnosis. My gp originally said I had pco and not pcos because all my testosterone, estrogen, androgen etc levels are within the normal range. The only abnormal blood test for me was insulin resistance, which wasn't picked up until my FS ordered a glucose tolerance test. I also had some longer cycles and day 21 (and 28 and 35) progesterone showed no rise indicating ovulation. Those two test results plus the ultrasound showing pco were what gave me the diagnosis rather than any other hormone issues. So not having all the other hormone issues means I don't have lots of the more noticeable symptoms you find on lots of websites.
Good luck, and I hope you get some answers or clarification at least.
