If you are already Rh-sensitized and are pregnant
Call your doctor immediately if you note a decrease in your fetus's movement after 24 to 26 weeks of pregnancy.
If you are Rh-negative
Call your doctor immediately if you:
- Think you may have been pregnant and miscarried.
- Are pregnant and have had an accident that may have injured your abdomen.
Who to see
A woman who may have problems with Rh incompatibility or sensitization can be treated by:
- A family medicine doctor, for mild fetal Rh disease.
- An obstetrician, for mild to moderate Rh disease.
- A perinatologist, for moderate to severe fetal Rh disease (hydrops).
If you test positive for Rh sensitization, your health care system or health professional may want you to be followed and treated by a perinatologist or an obstetrician who can easily call in a perinatologist.
