what you mention is RH incompatibility.Rh incompatibility is a condition that develops when a pregnant woman has Rh-negative blood and the baby in her womb has Rh-positive blood. Since Rh incompatibility is almost completely preventable with the use of prophylactic immunization
injection of RhoGAM), prevention remains the best treatment.
You will be given an injection of :: Rho immune globulin at week 28 of the pregnancy
. This desensitizes your blood to Rh-positive blood. You will also have another injection of immune globulin within 72 hours after delivery (or miscarriage
, induced abortion
, or ectopic pregnancy). The injection further desensitizes your blood for future pregnancies.
