Fleshing poking out of my vagina...

I am 37 weeks pregnant today with my second child.  While showering I noticed a fleshy part protruding from my vagina.  I tried to google and mainly was just seeing that it may be insides protruding because of the pressure of the baby.  Has anyone else ever heard of this or had this?  May call my doc tomorrow just to make sure but wanted to ask.  This never happened with my first and there is no pain or anything associated with it.  Sorry if tmi!
