I'm adopted and my birth certificates has my adopted parents name on it. Birth certificates get changed when adoptions are finalized.

well..i guess that's possible, maybe your grandparents or someone else in family also had negative Rh? my parents are both B, my brother is B and I am O xp there was a 1/4 chance that i would have O or something.. it's already rare that both you and brother both have O..you're just unique..let it go and accept that
