Krystle, dont feel bad about this. You cant help what you are feeling, and I think your reaction is just a part of your grief. I hope that your DH understands, and can be supportive and respectful of the way that you feel. Sure, he might be a little frustrated, but he is probably hurting too - even if he doesnt really show it.
After each of my losses I have needed plenty of time and space to sort things out before I was ready for sex again, let alone ready and willing to risk TTCing and getting pregnant again. Although doctors say that it is safe to try after just one cycle, it usually takes me a good two months or more to be emotionally and physically ready to TTC again. It can be hard to get intimate after a miscarriage, because it is just another reminder of what you have created together, but lost. I dont think this is something that is talked about very often, but I would guess that it is not uncommon.
If you have any more questions about if your feelings are normal, or how to deal with your grief and loss, please post again.
