Let me explain, I didn't feel good when I left the last message. You have O+ blood and your son has O+ and the father don't know. Ok, O+ is an universal blood meaning it can be given to people with A, B, AB,O, etc because it is universal. O+ can except blood from an O+ person if you need blood. Since you have O+ it can begiven to a child O,A,B, AB, etc. It can turn to any of the blood codes. It doen't matter what the father blood type is.
