Hi, welcome to HealthcareMagic
This is a situation of Rh incompatibility. Ideally, the mother should have been given Anti-D Immunoglobulin injection within 72 hours of the first delivery. Rh incompatiblity can cause anything from mild anemia
to severe jaundice
or still birth (erythroblastosis fetalis
). However, as Anti-D Immunoglobulin had not been given, all you can do now is have an obstetric scan done, to confirm the well being of the fetus and anticipate anemia or jaundice of the newborn.
