If mother is RH- and the baby is RH+ in most cases the blood will not mix until delivery. It takes a while for the mothers body to make antibodies that would affect the baby. You are more likely to have a healthy 1st pregnancy. Any pregnancy after that will result in more issues because of the antibodies waiting in the mom. This can cause the baby to have anemia, jaundice, or more serious problems. The problems will tend to get worse with each Rh-positive pregnancy you have.
During your first pregnancy, your baby could be at risk for Rh disease if you were sensitized before or during pregnancy. This can happen if... 1. You had a previous miscarriage, abortion, or ectopic pregnancy and you did not receive Rh immune globulin to prevent sensitization. 2. You had a serious injury to your belly during pregnancy. 3. You had a medical test such as an amniocentesis or chorionic villus sampling while you were pregnant, and you did not receive Rh immune globulin. These tests could let your blood and your baby’s blood mix.
