Quero ser capaz de ter filhos. Ajuda!

Hey, I'm 25 and I was diagnosed with PCOS three years ago. I have the Mirena contraceptive coil in and I find it the best treatment. It takes away the horrible cramps and messy periods and releases enough female hormones to regulate. Just thought I'd share. But the reason I am posting this I suppose is for some hope. I have been told by every doctor and specialist I’ve seen that it will be extremely hard to have children. Me and my partner really want to start trying and all I have seen and heard are horror stories. Does anyone have any advice or opinions on how hard it is? Any help would be much appreciated.
