It pees me off to hear of people being diagnosed with PCOS without so much as a full hormonal blood work up at various points in the cycle, let alone no US. PCOS is a whole syndrome, it is not a matter of one thing such as PCOs meaning PCOS, or late ovulation meaning PCOS. I would be really unimpressed with your doctor. You cannot make a diagnosis on blanket assumptions, it isn't right and it isn't fair to whack a label around when they haven't done any testing!

If it were me, I wouldn't be going back to see that person again. I hope the clomid works for you. But a question, do you ovulate regularly, despite your long cycles? Or are you cycles often anovulatory, do you know? I really wouldn't give the "diagnosis" a second thought, considering there was no real basis to make it!
