Will I go into labor this week???? I am 37 weeks and 4 days

I went to my doc for my appt. Last week and my cervix was closed. Today for another appt. I go back and I get checked and I am 3cm dialated. I have been more crampy here lately with more contractions and sooooo exhausted and back aching. I have also lost my mucus plug. Anyone else experience this and deliver soon? I hope she is here soon!
