As part of your prenatal care, you will have blood tests to find out your blood type. If your blood lacks the Rh antigen, it is called Rh-negative. If it has the antigen, it is called Rh-positive. When the mother is Rh-negative and the father is Rh-positive, the fetus can inherit the Rh factor from the father.This makes the fetus Rh-positive too.ensitization can occur any time the fetusâs blood mixes with the motherâs blood. It can occur if an Rh-negative woman has had: 1  A miscarriage. 2  An induced abortion or menstrual extraction. 3  An ectopic pregnancy.
What happens if there is Rh incompatibility during pregnancy? When an Rh-negative motherâs blood comes into contact with blood from her Rh-positive fetus, it causes the Rh-negative mother to make antibodies against the Rh factor. These antibodies attack the Rh factor as if it were a harmful substance.
