Being Rh negative means that you do not have Rh proteins on your red blood cells. But in your next pregnancy, the antibodies that you made when you were exposed to Rh-positive blood at your first birth can cross the placenta and attack the Rh-positive red blood cells, if your next baby has Rh-positive blood.Why is Rh negative rare?
