I have pcos as well. I've been trying to get pregnant for over a year and a half, and just a few weeks ago I found out I was pregnant finally. So it certainly is possible to get past that hurdle.
I had tried for years. When finally dx with PCOS my dr put me on Metformin. I got pregnant 3 weeks later and now have a 2.5 year old little boy. It is very possible.
