Blood group related question during marriage

Patient: Hi doctor if my blood group is O+ , then is it ok if I will marry to O+ girl

Doctor: Hi,Thanks for the query.I understand your concern.If the female is having Rh negative and male is Rh positive that can lead to few problems but usually Rh positive blood group person marrying another Rh-positive person may not lead to much problem.So, you may not have blood group-related problems in future.Take care.
