Does O positive blood affect pregnancy?
Unlike Rh incompatibility, ABO incompatibility during pregnancy is rarely a problem — even when the mother’s ABO group doesn’t match the baby’s ABO group! In situations where a mother has Type O blood, and the baby has A, B, or AB blood, the mother’s immune system will recognize the baby’s blood as foreign.
What are the benefits of being O positive?
