I am sorry for what you are going through. I have been pregnant six times, but I have only had three children. The last MC nearly ended my marriage because my hubby did not understand. I called a really good friend and leaned on her for support and understanding. It was tough, but we came through it.
I would suggest that you and your spouse go talk to your doctor together. Ask your doctor specifically about the emotional side of a MC and let your hubby hear what it actually means from the doctor. He will be able to understand and help you better if he hears it from a professional. It is annoying, but this tends to be the way a guy's mind works.
Good luck, this is hard, but not impossible.
