I have pre-PCOS and you know what? Diet and controling insulin weren't enough for me. I needed metformin for a few months until my diet and weight and activity level were enough to control my insulin. Then I needed tamoxifen (like a mild clomid with smaller chance of multiples) and a shot of HCG to make me ovulate properly. This meant ultrasounds and tons of blood work, and I would do it over again in a heartbeat. It was so worth it. I know it's hard and frustrating. Hang in there, and I am not one to even take tylenol, but in this case, it was what I had to do and I have no regrets. But you need to work with the right doctor. Just metformin is often not enough.
