Discouraged :(

I'm 41 y/o and my fiancé have been "trying" unsuccessfully for a year now. Starting to believe I truly missed my chance to be a mother. I feel like I'm one of those woman that aren't meant to have their own children but to love other couples kids. 
I don't know what if any treatments would be available to me that are covered by my disability insurance and not sure where to seek advice.
