How does blood type affect pregnancy?
A fetus may inherit its Rh factor (either positive or negative) from either parent. There may be problems if you’re Rh negative and carrying a fetus with blood that’s Rh positive. During your first visit to your obstetrician, you’ll take a blood test to determine your blood type and screen for antibodies. If your body reacts to Rh-positive red blood cells, your anti-Rh antibodies can begin to attack the fetus’s red blood cells. To prevent this from happening, you’ll receive Rh immunoglobulin (RhIg). RhIg is a medicine that blocks antibodies from attacking the fetus’s blood.
