If a RH- person gives birth to an RH+ baby, the RH- mother MUST get a rhogram shot twice. This is to prevent the mother's body from creating a resistance to the future RH+ babies the mother may have. It is like getting the flu the first time, after you get it once, the body prepares itself to fight it the next time. In this case, if you were to NOT get the rhogram shot, if you got pregnant with another RH+ baby, your RH- blood would "dispose" of the baby..... It will treat the baby like a virus and will attack it.
They have to do this anytime your blood COULD mix with the babies, such as miscarriages, amniocentesis and birth. If they can't find out your blood type, they will draw blood to make sure to find out if you need the shot of not....
If you are RH-, the doctor will make sure to get you the shot. They know what happens if you don't get the shot within the certain time frame. They know that and will give you the shot if you need it. They will also give you a card to show that you did get the shot.
If you are positive, you can have either type baby and not have any problems with the shot or not....
Positive can have both with no problems, but negative can only have negative, UNLESS they get the shot....
It does not cause diseases in the baby. It is only determining whether the mom needs the shot or not to have future kids........
Any other question, e-mail me.....

My mom, RH-, personal experience
She got it three times, twice after kids, once after miscarriage
Myself, RH+, personal experience
never had it, but after my miscarriage, they could not find my blood type, so they drew blood to make sure I didn't need the shot....
