During any pregnancy a small amount of the baby's blood can enter the mother's circulation. If the mother is Rh negative and the baby is Rh positive, the mother produces antibodies (including IgG) against the Rhesus D antigen on her baby's red blood cells.
If you're Rh-negative and your baby is Rh-positive, your body will react to the baby's blood as a foreign substance. Your body will create antibodies (proteins) against the baby's Rh-positive blood. These antibodies usually don't cause problems during a first pregnancy.
