I found out my first little angel had no heartbeat at 10.5 weeks and had a D&C at 12 weeks (that was in July 08). In February 09 I finally got pregnant again, now I'm 22 weeks with twins!
I can tell you that I went through a rollcoaster of emotions that felt unbearable at times, and I was relatively ok at other times. I'd think about it the most coming up to my period then I'd cry the most during the week of my period. I didn't really begin to heal until January, when my little angel would have been born. This was a bit of a turning point for me and I started to feel human again, then the next month I got pregnant.
I'm so so so sorry you had to go through this, I think you just have to take the time to mourn your loss knowing the lots of people get pregnant again after a D&C. The new babies won't replace my first little angel, but it does make it a lot easier.
If you ever need to talk, feel free to PM me, I know it helps talking to someone who understands, often friends who haven't been through it don't understand what you're going through but there are heaps of others who do.
Hold onto the fact that you CAN get pregnant... at least you know this!
