You should probably get a Rhogam shot at 28 weeks and after pregnancy (ask your doctor), because there can be complications if you and your baby have different blood types. Read http://www.myspace.com/reneeisonegative
which is all about it. This also has some good answers on it about it

So the previous answer of:-
"It's definitely safe. The child will end up with an O + or - blood type. It's all up to chance."
is mainly true if you get the shot and are monitored, but its not as simple as they make out.
no but they will have b.o.
It is possible for there to be problems with a pregnancy. If mother's blood type is negative and the father's is positive, and the baby is positive, her blood type may begin to attack the child. Make sure she checks with her doctor regularly during a pregnancy.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
No.
Yes.
# yes, if father is + - for RH and mother - - (negative) or + - (positive); the father can generate sons A, B, or AB depending by mother's group.
no
yes
o positive
no
No
Yes. The father's phenotype is AO+*; the mother's is OO--.
If mother is heterozygote yes.
