Hi, Im so sorry this has happened to you. I was in a similar position to you last year(year before??), but I already had 2 children so it is slightly different.
I had a missed m/c at 12 weeks, no warning just bleeding. I think I recovered pretty well but then a couple of months later, I got pregnant again and 'tracked' my pregnancy week by week, at 10 weeks they said it was no longer viable, even though I had been watching it grow every week That is hard, isn't it. I too had a d&c, but I'm still upset about it now. I had got to the stage where I thought I wouldn't be able to carry any more children.
Immediately after, I got pregnant again, I bled at 5 weeks and started to give up again, but it turned out to be a haematoma. I still bled throughout the pregnancy, but was convinced that I would lose the baby. I didn't and he's a healthy 5 month old now, but I refused to accept him for a while.
I really feel for you, and hope that one day it will happen
Perhaps when/if you decide to get pregnant again, you may think about not having any early scans done. I know that sounds odd, but it was hell for me going back and forwards to the hospital to see if my baby was there, IYSWIM? At least hold off until 8 weeks or so, as with a heartbeat, chances of m/c are under 1%.
Keep talking about it, even if it's on here, because it will just fester in your mind. That was my biggest mistake. Telling everyone you're fine...etc. I believe my m/c has contributed to my PND, so please try to talk it through.
Sorry for waffling, just wanted you to know that you are not alone. The conception boards would be good if you do decide to try again.
