missing plug

Dana
I lost my mucous plug (assumed completely because of the quantity in one go) last week (just before 32 weeks). My OB did CTG and fFN and said I'm clear for another two weeks (ie. Should be safe from preterm labour). Has anyone previously lost their plug early (this pregnancy or previous) and made it to term?
My first pregnancy was pretty standard - slightly overdue, regular contractions followed by plug loss, then blood, then baby arrived same day.
I'm trying to be "realistic" about the situation but I seem to flip between perhaps being "too" relaxed about it to becoming quite worried. I know that everyone is different, I'm just curious about personal experiences.
