What are the consequences if my husband and i are the same blood group?

None: This shouldn't have any affect on pregnancy.

None: There aren't any negative consequences.

Probably none: Having the same blood group is not a problem. The rh factor is important. If one parent, is negative and the other is positive, there is a chance for problems. Ob/gyn's routinely check for problem and will give the mom a shot called Rhogam prior to deliver.

None: It is of no consequence.
