My husband and I have been trying to get pregnant for two years now. All doctors said that I'm good to go, but the problem iz, I think I might have PCOS. I've never been diagnosed with it, but there's a chance. Could this be the reason all attempts have resulted in negative tests? What should my next step be? I don't want to take fertility drugs. I want it to be all natural.
