ttc after miscarriage

Nikki
I found out last week that my babies heart beat had stopped around 9 weeks, I was due to have my twelve week scan yesterday. It broke my heart and was a terrible thing to go through. Me and my fiancé really want a baby and I almost feel bad for wanting to start again right away. Anyone else feel like this? Also how long did it take for you to start trying and to get pregnant again? I'm really worried incase something bad happened again.
