ttc with pcos

im 21 with a 3 (almost 4) year old step son. ive had baby fever since before i even knew what sex was which is why im a nanny. When I was 17 I got told that I had pcos ( polycystic ovarian syndrome) I've been ttc the past 2 years naturally ( taking prenatals, using preseed lube) and haven't had anything happen. I'm looking into talking to my ob about trying medications or something different but I don't even know what to suggest I do.
