My first baby was born by emcs so I have been watching lots of childbirth videos to prepare for the next one.
I've noticed, especially on waterbirth videos, that after the baby's head has come out a bit of blood usually follows. Does that mean that the mother has torn a bit or is there just a little bit of blood that comes out anyway? If the latter, where does it come from? Is it the same as the mucus plug having some blood in it?
