Does losing a chunk of mucus plug mean anything at 37 weeks??

I lost a large chunk of my mucus plug this morning but there was no blood and no contractions. I had really strong Braxton or false contractions last night off and on, nothing consistent and nothing today.

When did you lose yours or have you lost it and went into labor yet?

** I had my first daughter at 38 weeks and this one is measuring a week ahead.
