So frustrated-help please

Sarah • New mama to my baby boy born in September 2015
I had a miscarriage in June that required a D & C. It took almost 60 days for my first period. Then I had a normal period at 35 days. We  have been trying again for 2 months and I'm now on day 38 and had a BFN on day 35. I just feel so frustrated like everyone else is having babies I feel like my body is failing me any suggestions or ideas?
