We just found out after a miscarriage that my wife has rh negative blood and also has rh antibodies. She got these antibodies due to a former pregnancy that was aborted and the clinic did not check her blood type and give her the shot she should have had. My question is this... if I am positive blood type and she already has the antibodies what chance is there of us having a successful pregnancy in the future and what health problems specifically have these pregnancies ended up having for the child?

There is possibility of successful pregnancy. Consult good doctor and they give a specific injection to people who have rh negative factor during delivery.
