I've never heard of the m/c association. I have had a book called "Miscarriages, Why They Happen, and What you can do to Prevent It." I can't remember who wrote it, as I only borrowed it from the library. I find the library to be the best place to look...cuz they you don't have to buy something that may not be that helpful. I also had a religious m/c book that brought comfort to me.
