Recently had a miscarriage.

Shannon
I am 23 and My husband and I were pregnant with our first child and unfortunately I had to have a d&c performed on 4/14/2015. The doctor said I at least needed to wait until one cycle. I had my period about two weeks ago and my husband and I have started trying again. I am worried that If I get pregnant again I may have another miscarriage. I won't a baby so bad. Any advice on how to calm my nerves down and conceive fast?
