Is thr any problem to be pregnant if i have AB+ and my wife has B- blood group?
Since your wife has a negative blood type she is called “RH Negative” and will need to get a shot called a RhoGam shot. I had to go through the same thing. When the woman is a negative blood type and the father isn’t then the baby could be either. Well for some reason only women with negative blood types have the problem where if their baby is a positive blood type then their body starts to build up antibodies against the baby and the next pregnancy she has her body will fight off the fetus as it would an infection. She just gets a shot towards the last 1/3 of her pregnancy and then if the baby was born with a positive blood type she would get another shot after giving birth, but if the baby had a negative blood type she would be fine. Here is a link to a site with some more info! Hope it helps!
