Does being Duffy Positive and MNS+s+ Blood groups if you are African-American woman have a baby with someone with the same blood type?

If an African-American woman is duffy positive and MNS+s+ would it make it easier and safer to have a baby with someone who has the same blood group than someone who is Duffy Negative and MNS-s+ Or MNS-s-?
Update: If I were duffy negative could I have problems if I were with someone who is duffy positive vs duffy negative?
