<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello Doctor, we both have same blood group A negative . we want to know whether our future child would also avail this blood group ? Would this cause anything harm or side-effects after sexual intercourse ? or pregnancy problems..? Please advice  <response>: Hello dear, I understand your concern. In my opinion there wont be any problems either after sexual intercourse or in pregnancy as you both have negative group. The baby can be either O or A negative. But definitely negative group. The problem arises when mother is negative group and father is positive group. Here when the fetus is positive group it sometimes doesnt get adjusted with negative group of mother. This doesnt occur in your case as definitely fetus will have negative group and mother is also negative group. So relax. Best regards...
