Trying Again

Hi everyone! I am 23 and my husband is 26. We got married last October. I was on birth control continuously for 4 years with no periods. So I went off the pill after our wedding. We started trying shortly after our wedding and became pregnant right away. However I lost our baby. At 9 weeks I had an ultrasound that showed no heartbeat. I had to have a D&C and doc told us to wait a cycle or two before we try again. So I had a cycle and now we are starting to try again. I'm so nervous and worried. I want a baby so badly I've always wanted to be a mom and I'm afraid I will miscarry again. Anyone have any advice to offer? Thanks!
