Ok, umm whats rh negative/positive?

anonymous · Answer

The mother's body may make antibodies to the Rh antigens in the baby's blood. This means the mother has become sensitized and her antibodies may cross the placenta and attack the baby's blood. Such an attack breaks down the fetus's red blood cells, creating anemia (a low number of red blood cells).
