Question: my blood group is O positive and my wife is A negative but my baby blood group is O positive is there any problem
Answer: Hi. No tbere isnt much problem.
Your wife muat have got a anti D injection within 72 hours of delivery because baby and mother are of different blood group.
Generalk second pregnancy is bit risky if mother and fetus has differnt RH(-).
But that too are resolvable doctors would guide your in next pregnancy.
I too am a rh(-) mother witj rh(+) child so dont worry.
