It's my second pregnancy, and my husband and I have different blood types. I am going wed to see if I was synthesized 5 years ago with my sons birth. I'm freaking out Googling all the possibilities of having an rh disease child. Is anyone else dealing with this? I read people who are also abo incompatible have less chance of becoming rh sensitized and we are also abo incompatible. I hate being such a worrier.
