Came across this article this morning and I found it really interesting and pretty encouraging, believe it or not. It kind of explains my family history of recurrent MC too, if you think about it. Basically it says that women who experience multiple miscarriages are actually so fertile that their uterus allows for fertilized eggs to implant where as women of normal fertility would not be implanting these eggs....
