Rh incompatibility rarely causes complications in a first pregnancy and does not affect the health


Rh incompatibility rarely causes complications in a first pregnancy and does not affect the health?
why does it not affect the health of the mother or child in the 1st pregnancy? I understand why it does affect it in 2nd and beyound pregnancies! Help

1 :
If the blood from the Rh+ baby mixes with the Rh- blood of the mother the second pregnancy can be complicated because the mother's body will treat the 2nd fetus as a foreign body and try to get rid of it, causing miscarriage or birth defects. It does not happen with the 1st pregnancy because the blood does not mix until birth of the 1st child.
2 :
Because after the first pregnancy your body develops the antibodies that attack the fetus. You don't have those antibodies with your first pregnancy.
