10 Νοε 2022 · Rh factor incompatibility only becomes an issue during pregnancy when you’re Rh-negative and the fetus is Rh-positive. Your provider treats Rh incompatibility with an injection of Rh immunoglobulin (RhIg).
During a pregnancy, Rh antibodies made in a woman's body can cross the placenta and attack fetal blood cells. This can cause a serious type of anemia in the fetus in which red blood cells are destroyed faster than the body can replace them. Red blood cells carry oxygen to all parts of the body.

In a first pregnancy with an Rh-positive fetus, the baby often is born before the woman’s body develops many antibodies, so there may be no serious problems. In a second pregnancy with an Rh-positive fetus, these antibodies are more likely to cause anemia in the fetus.
Rh sensitization normally isn’t a problem with a first pregnancy. Most issues occur in future pregnancies with another Rh positive baby. During that pregnancy, your antibodies cross the placenta to fight the Rh positive cells in your baby's body.
