Read This! If You Have a Negative RH Factor

We care about your reproductive health, so it is important to discuss something called Blood Rh Factor. Your Rh Factor is essential to know, especially during pregnancy.

There are four types of blood: A, B, AB, or O. In addition, blood is classified as Rh-positive or Rh-negative. Your doctor can test your blood to determine if you are Rh-negative. Being Rh-negative and pregnant with an Rh-positive baby can negatively affect future pregnancies if not treated properly.

An Rh-negative woman who delivers an Rh-positive baby has a miscarriage or an abortion of an Rh-positive fetus may become sensitized to the Rh factor. Sensitization to the Rh factor does not affect her health during pregnancy. However, this sensitization could dangerously affect any Rh-positive children she may have in the future.

When a pregnant woman is Rh-negative and her baby is Rh-positive, her body may generate an antibody that can damage the baby’s red blood cells. She can receive an injection known as  RhoGAM (Rh-immunoglobulin) to stop antibodies from forming. 

Rh-negative women should receive a RhoGAM injection after any miscarriage, ectopic pregnancy, or induced abortion to prevent any chance of the woman developing antibodies that would attack a future Rh-positive baby.

If you are Rh-negative and planning to take the abortion pill, it is unlikely you will be able to determine the baby’s blood type that early in pregnancy.  It is important to speak with a doctor to avoid Rh incompatibility in the future.
