I’ve been TTC with PCOS & nothing..

As you can tell from the title, I’ve been TTC for a while with PCOS. I’ve wanted to try naturally just to see if I could make it happen. My periods are both regular & irregular. I have some months we’re it’ll come once a month then other times it will stay gone for up to 2 months until it comes back. I don’t know what I should do. I want to go to the doctor to see if they could help but I feel like since I’m 19, almost 20 that they will just tell me that I’m to young to be trying, that I have to wait another year or put me on birth control to regulate my cycle. Does anyone have any advice that could help me? Anything they’ve taken or done to help them conceive??
