I didn't lose mines either and they broke my water at 10 cm dilated !!

I never lost mine and my water never broke.

Nope. I lost mine about three weeks before I went into labor. I lost it at 38 weeks, and went into labor at two days shy of 42 weeks.

nobody actually knows .... it could be hours could be days or even a week

Nope. mucus plug isn't an indication of impending labor, bloody show is.
