In addition to what has been said on this i want to add that there is what is called Rh Incompatibility/Isoimmunization-a Rhesus Negative woman getting pregnant for a Rhesus Positive Man;if the foetus inherits the Rhesus Positive blood factor from the father, the Rh- blood of the mother can be sensitized to develop antibodies against the Rh+ factor of the Rh+ blood. The 1st pregnancy MAY escape unhurt, but subsequent pregnancy that has Rh+ blood will be at risk of massive destruction of reb blood cells with resultant intruterine death if the mother was not given Anti D injection after the first baby. Rh- woman can marry Rh+ man she will need to be given Anti D injection after delivery of first pregnacy within 72 hours. There are tets to know the Rh status of the baby in the womb. If the baby is Rh- like the mother , the mother will not need any anti D injection after delivery-Dr Akinwilly |
