Hi Candace. I'm so sorry for your losses. (((HUGS))) But if it makes you feel any better, you're not alone. I can relate all too well to what you're going through. I've had two losses myself. One in May '09, and the most recent this past June.
During my first pregnancy, my sister-in-law was also pregnant. She was about four weeks ahead of me. After I lost mine (at 10wks) I remember how difficult it was when she would excitedly tell me about all her big pregnancy milestones. I was happy for her that everything was going well, but at the same time it just devastated me. It was all very painful reminders of what I should have been experiencing for myself. She went on to have a healthy baby boy and my nephew is now 19 months old. And even now when I see him doing something new, I often catch myself thinking "my little one would be doing those same things soon too". It makes me a little sad, but in a way, it's good. I get to watch my baby grow up through my nephew and I consider that such a blessing.
As far as husbands go, yes, they do deal with things much differently than we do. I have to give my DH a lot of credit, he was extremely supportive after our first loss. But after the second, well.... not so much. I feel like it's hardly phased him at all, while it's still something that is constantly on my mind. He just doesn't understand why it's not as easy for me to move on. I wish it was, but it just doesn't work that way....
I don't come to this board very much, but if you need someone to talk to, you can find lots of support on the Trying to Conceive After Loss board here on WedMD. That's where you can normally find me too (although since my most recent loss, I've mostly just been lurking). Feel free to post there, even if you decide to stop TTC for a while. There's lots of wonderful ladies there who can offer understanding and encouragement.
I wish you the best of luck and pray there will be good things down the road for you!
