labor around the corner?!

I need some opinions or advice on if I'm going into labor anytime soon. I'm 39w 5d today and yesterday I had my prenatal appointment and measured 2cm and 80%. During the appointment we did a membrane sweep and then I woke up today and lost my mucus plug. Does this mean I will going to labor soon? Either on my due date or earlier!? I'm a ftm so any advice or opinions will help out!!
