As all the others have said PCO is not the same as PCOS, not everyone with PCOS needs help falling pregnant and if they do there are several options before IVF. Also PCOS can come and go from what I understand - there have been follow-up studies on women with PCOS and 5 years later some of them no longer meet the diagnostic criteria even without weight loss.

As for my story, I was diagnosed with PCOS last year after 6 - 7 months TTC with very irregular periods (ie. one every 3 or 4 months). I started clomid as there were no other issues for me (normal weight and sugars), conceived first cycle and am now 35 weeks pregnant.

So don't stress about IVF at the moment. Try to be a normal weight, exercise and eat healthily as we all should be doing all the time anyway. Then hopefully when you do want to conceive you'll have no problems.
