Simple, clear guidance — what matters for marriage, and when pregnancy needs medical care (Rh factor).
- Marriage: No blood-group combination prevents marriage.
- Conception: Blood group doesn’t affect ability to get pregnant.
- Main medical concern: Rh incompatibility — only when the mother is Rh negative and the father is Rh positive.
- Prevention: Anti-D (Rho(D) immunoglobulin) injections during pregnancy and after delivery prevent complications.
