Mucus plug with second baby.

Katie
I just lost my mucous plug about 20 minutes ago and I'm currently 37 weeks and one day pregnant with my second baby. When I was pregnant with my son who is 19 months old whom I delivered at 39 weeks, I lost my mucous plug exactly a week before he was born. Do you mommies think I should be concerned that I may go into labor early or do you think it will be like my pregnancy with my son and I am good for another week?
