super frustrated

Don't know what's next ... been trying to get pregnant since last March and have not been successful. I had Mirena for a few years before because of a miscarriage and got scared of going through that again.. now every month is so discouraging when I hope to miss my period but there is it. 😞😔 today I cried my guts out by myself not finding the answers to the million questionsy mind comes up with 
Any advise?
