Can individuals with Type A blood who are Rh-negative become pregnant?

Patient's question:

No

Doctor's answer:

If you are Rh-negative and pregnant, you need to receive an injection of anti-Rh-r immunoglobulin at 28 weeks of gestation to prevent pre-delivery allogenic immune response. If your baby is Rh-positive, you should receive another injection of anti-Rh-r immunoglobulin within 72 hours after delivery.
