Feel really low

Came off depo provera 7/8/15 had what appeared to be a missed mc 19/4/16 no luck since period was 5 days late then when it came it was relatively light only one day medium just down because we want a baby so bad with my previous children I concieved within 2-3 months (different partner) my partner is scared incase it's him which I doubt due to the mc just waiting for the day we get out solid bfp but feels like we been waiting a life time almost a year :( has this happened to anyone else?
