Lost my mucus plug - how much longer now??!

Aly
So my due date was two days ago, and last night I started having some very mild contractions that were regular for the first time (every 10-20 minutes.) I had had Braxton Hicks before, and these weren't painful, but felt different. It went on for about two hours - or maybe longer, but I fell asleep. This morning when I used the restroom, I noticed that I was starting to lose my mucus plug! Over the next few hours it came out completely in the restroom and shower. Now it's been almost 12 hours, and I keep having these mild contractions that don't hurt.. my tummy just gets really hard.. and am soooo excited for the actual labor to start! 
How was that for you ladies? How much longer do you think until our baby is here?
