Is it true that having B RH NEGATIVE blood type makes you more prone to miscarrages?
it does not usually cause miscarriages however ABO RH blood types can lead to serious medical issues, the Rh factor, like ABO factors. The greatest problem with the Rh group is not so much incompatibilities following transfusions (though they can occur) as those between a mother and her developing foetus. Mother-foetus incompatibility occurs when the mother is Rh- (dd) and the father is Rh+ (DD or Dd). Maternal antibodies can cross the placenta and destroy foetal red blood cells. The risk increases with each pregnancy. The first time an Rh- woman becomes pregnant, there usually are not incompatibility difficulties for her Rh+ foetus. However, the second and subsequent births are likely to have life-threatening problems. The risk increases with each birth. In order to understand why first born are normally safe and later children are not, it is necessary to understand some of the placenta’s functions. Nutrients and the mother’s antibodies regularly transfer across the placental boundary
