Hello, I have gone through the query and understood your concern. You are experiencing Rh incompatibility and its outcome, which results in premature births and abortions if not properly treated. If the first child is born with a negative blood group, the risk of sensitivity is less. Yet, immunization of the mother is mandatory after the delivery or during next pregnancy with anti-D immune-globulin. In the current scenario, please see a specialist in high risk pregnancy, before you plan another pregnancy, to plan further management. Repeated unhealthy pregnancies only lead to increased risk of another failure and also deteriorate the mother s health. Hope you find this information useful. Take care.
