If You Are Rh Negative
If you’re Rh negative, ask your doctor about getting treated with RhoGam. Even if you miscarry or don’t deliver the baby, you will still need treatment. The health of any baby you have in the future depends on it.
When Are You Treated?
If your blood has not formed Rh antibodies, you’ll be treated during week
Preventing Future Problems
Your chance of forming Rh antibodies increases with each pregnancy. That includes ectopic pregnancy (the fertilized egg is outside the uterus) and pregnancy that ends in miscarriage or abortion. In these cases, you should talk with your doctor about getting a RhoGam injection. This is because your body can make Rh antibodies even if you don’t deliver a baby. Rh antibodies can cause problems in future pregnancies.
If You Have Rh Antibodies
If antibodies have already formed (sensitization), RhoGam can’t protect the fetus. You and the fetus will need special care during pregnancy. Your health care provider will explain the details to you.
