You should have your sons blood retested. Since you have an AB blood type your son should be either A, B or AB. AB is always dominate over O in blood typing.

It's not possible. Either the test was wrong or your baby was swapped at the hospital.

Baby was with us all the time and anyway he was the biggest baby, what surprised everyone at hospital. I read something about Bombai fenotype which means my husband is probably special type O called HH type which has hidden type A or B or both. But not sure I understud it.

What the father is is irrelevant. You have one A gene and one B gene. Those are the only two possibilities you could pass on to your child.

The only way for a person to be blood type O is to have NEITHER an A nor a B gene, but to inherit an O from the mother AND an O from the father. It IS NOT POSSIBLE for any parent of blood type AB to produce a child of blood type O, regardless of the blood type of the other parent.

Well, testing can always be wrong. But it is not unusual for a baby to have the blood type of the father instead of the mother. Just because you carried the child does not mean it will have your blood type.

But everywhere says AB mum cannot have a baby O whatever group father is. My problem is if my son RH is really negative,because of this they did not give me the antiDOT injection after birth. Now I am again pregnant and every day Im not feel well.

Your first child is negative as are you and your husband. You only need the shot if your baby is Rh+ and since you are Rh- and your husband is as well you can only have Rh- children with your husband. You're not feeling well as nothing to do with blood type.

Talk to your doctor about other causes.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
