I am very confused. I just looked at the card I received when I was born in regards to my blood type. On the line that reads "Blood Type:" it says "O negative"... but on the line that says "Rh:" it says "Positive"... how is this possible?? I really don't understand... does it mean I am O negative and carry the Rh gene? My mom is O positive and but I don't know if my dad is O + or

Does anyone know how this works?
