I've been reading this thread for the last hour or so and indulging (like the woman who said she felt like she'd been eating mars bars!).
I can relate to so much that's being said here...the pain, the anger, the horror of it all. And, perhaps more importantly, the hope.
I had 3 mcs before my DD was born 6 years ago. I had another MC around 18 months ago and I thought it wouldn't hit too hard, with having a child already, but it did. Losing a baby will always be losing a baby, no matter what stage it was at or what situation you were in. And I think you're always entitled to grieve...even if it was years ago.
I'm like the husband who doesn't remember the due date for his lost child. I don't remember the dates of any of mine. It helps...though I still feel sad occasionally and realise that it ties in roughly with one of the four due dates. I don't think you ever forget on a subconscious level...and why should you??
For you new parents to be, I wish you luck with your future pregnancies. It isn't always the case that 1 MC automatically means there'll be more, so take heart. If you are unlucky enough to be a multiple MC person (like myself!) you can still get lucky. My DD is currently going through a cheeky phase and driving me nuts...but I love her more than I can say and feel totally blessed to have her.
Take care of yourselves and good luck with the next PGs.
