Ahhh, the wonderful rainbow of colors of discharge when about to give birth. :>) I never 'lost a plug' which is what I looked for when going into labor but instead, had lots of different colored discharge prior to giving birth (like the few weeks leading up to it). Yellow, pink, tan, orange, pretty stuff.
So, yes, that can be part of all of that 'stuff' coming out. good luck hon
Experienced mamas, any advice?
