Your blood type actually makes you a universal recipient, meaning you can receive ANY type of blood. Most blood contains antibodies that limit the types of blood that can be given. For example, someone with type A blood has antibodies against the B antigen, and someone with type O blood has antibodies against both A and B antigens. But since you're AB, your blood contains no antibodies (against either A or B). Therefore, you can receive type O, A, B, or AB blood. Your blood is also Rh positive. This means that you can accept blood with or without the Rh factor. So basically, you have nothing to worry about, because no matter what blood type you receive, your body should accept it.
