  • It's not blood type. It's the rh antigen. Here is a link for you:

  • It's not blood type but the RH factor, positive or negative, it's only needed if the mother is RH- and the baby is RH+

    What happens is that if you have any other babies who are RH positive, and you have had a previous RH positive baby and DID NOT get the RhoGam shot, you run the risk of your body attacking the baby (and possibly causing miscarraige) as a result of the antibodies built up against the RH factor that were developed during the first birth. Any RH NEGATIVE babies would not be affected by you getting/not getting the RhoGam shot.

  • so your antibodies will recognize babies blood type, and not attack it.

  • They give you the shot not if your blood type is different but if you RH ( the negative or positive) is different. It can cause alot of complications for mommy and baby cause your bloods wont react to each others properly.

  • negative blood types tend to reject the baby, it can view it as a harmful substance to the body, but only if the baby is a + factor. If the baby bleeds inside of you.. for whatever reason... that can cause you problems and for your body to attack itself. I have never heard of that being a problem if you are a + blood type. I am - and have had the shot 4 times in my life and i'm only 23!!
