Symptoms

If you are already Rh-sensitized or become Rh-sensitized while pregnant, you will not have any unusual symptoms.

Fetal problems from Rh sensitization are detected with Doppler ultrasound testing and sometimes with amniocentesis. It is possible, however, that a fetus with severe Rh disease will move less frequently than it did earlier in the pregnancy.

Other conditions with symptoms similar to Rh sensitization include other blood type incompatibility problems and fetal infections.
