Mucus plug?

Bethany

I have never been one to have a lot of CM or discharge of any kind. My vagina has always been on the dry side except during ovulation and even then there was never much. Today, at 34 weeks and 3 days I wiped and wiped and wiped sooooooooooo much from my vagina and all I can wonder is if it is my mucus plug or not. It was completely white, thick, but also slippery...not like phlegm mucus you cough up when sick. It reminded me of wet frosting. Is it just regular CM since there was no blood?
