Your blood type contains more than one part.
You can be A, B, AB or O.
Then comes the part with the Pos or Neg. (Rhesus factor) Which simple means that you are pos or neg for an Antigen that's called D.
If you are pos you can receive Rh neg blood.
If you are neg you can receive Rh pos blood, but the chances are that you may develop Antibodies to the D. Which is not dangerous as long you are not receiving more pos blood later in life. The question for the Md is, if no neg blood is available are we risking the possibility of a later developing Antibody or are we letting the patient bleed to death? You take the Antibody!!!
So, with you question in mind you have possible a blood type
O Rh pos, or something matching.

Type O blood has no surface antigens on it for your bodies antibodies to attack. Therefore, type O blood is considered the universal donor.
If you are type A blood, you have type A antigens on your blood that your body recognizes as self. If you got type B or AB, the B antigens would be recognized as foreign and attacked.
