Hi TCM,
Welcome to BB, sorry to hear of your loss. I have also had a m/c recently and started bleeding on the 31.12.07. I should have been 10 weeks, but found out that it was a missed m/c and the baby had only made it to 7 weeks. I know what you mean about DH being excited, as we were looking at prams before X mas, and even bought a huge new car!
I think that many men like to adopt the 'if I pretend everything is fine, then it will be' approach to surviving loss. DH changed the subject every time I bought it up, and I needed to look to my friends when I wanted to talk about what happened. A friend of mine who lost a baby at 12 weeks said that it was the same for her and her DH.
I dont really know what to suggest. Maybe you could ask him how he would feel if you became preganant again soon? As for DTD, I did not have a D&C, but was told to wait until the bleeding stopped, to reduce the risk of infection. I have actually been spotting on and off all month, so decided not to wait for that to stop!

Good luck honey, maybe I will see you in the TTC after mc and loss forum?
Take care,
C
