has anyone tried

I have pcos and I heard it's going to be very hard to get pregnant (which sucks). im on birth control, metformin and a pre natal vitamin. my obgyn prescribed me. I stopped taking the birth control hoping I would get pregnant. hasn't happened yet. my friend told me to try the Diva cup!!!! has anyone else used it and had any luck? or have any other things we can try? we want a baby so bad.
