how much mucus plug do we have? I was told I'm 2 cm dilated yesterday and I been loosing pieces of my mucus plug and then big globs and I just lost a big gold today sorry tmi but still no streaks of blood in it like everyone been saying it's just a light brown yellow color. is it suppose to have blood all the time or some people's don't? I also been having contractions and they are getting closer together. but not 5 mind yet and least 1 to 2 mins.
