advice on miscarriage & trying again

Alesia
I was told I'd never get pregnant but to our surprise we got pregnant this year in February but miscarried April 2nd. We have been trying ever since and having no luck. I used glow this entire time, only took two cycles to get pregnant but this time I'm just having the worst time conceiving. I also didn't have a d&c because I passed everything and had no problems or infections and even got my period within two weeks of the miscarriage. could something be wrong that I don't know about?
