Hi!
I can understand your concerns since you have tested as Rh negative. If both you and baby's father have same blood Rh type (either positive or negative), then chances of any antibody formation is less. When mother is Rh negative and father is Rh positive—with the result that the baby can be Rh positive. The first baby usually is spared as the antibodies develop slowly. Thereafter the anti-D antibodies stay for life and cause miscarriage if the baby in womb is Rh positive. Rh –ve babies are spared. Hence anti-Rh antibody Injections are given to suppress this immune response after first miscarriage or childbirth to prevent subsequent miscarriages. After the first baby is spared, subsequent full-term pregnancies are then possible even with Rh +ve babies. Hope this helps. Take care!
