Reply to comment by neobeguine in TIL, the placenta that forms with a fetus isn't created by the mother. It grows from the fertilized egg and some fetuses actually develop outside the uterus attached to the intestines in the body cavity. by darw1nf1sh

And you end up with a rhogam shot injected directly in your ass cheek.

Yep. I'm A- and my husband is A+. Thankfully, rhogam exists! Both my daughters are A+, so they won't need it if they choose to conceive.

Something I learned when it happened to me is that they make rhogam for when this happens with Anti-D antibodies but there are other antibodies your baby could have like Anti-E and Anti-K (Kell) that they don’t make a shot for! It can be very dangerous.
