39 Weeks and Early Labor???

Last night I started having very painful contractions every 5-10 minutes.  I was moaning, huffing and puffing and even screeching at times. Finally after two hours I gave up sleeping and started cleaning instead. The contractions continued but I just kept working through them. Around 3am I started losing my mucus plug. Then about 5am the contractions  tapered off and I slept for a couple of hours. Throughout the day I've continued to have bouts of painful contractions but nothing regular. I'm going to try and get some sleep now. Hopefully baby makes an appearance this weekend because these random bouts of painful contractions are getting brutal.
