TMI Picture... Did I Lose My Mucus Plug?

So I hate posting a picture like this, but I'm so curious! Almost every time I go to the bathroom, I have extra mucus and some blood....probably the last 24 hours. So is this what a mucus plug looks like? 
I'm 37w 2d and have been having a lot of contractions. I'm also 4cm dilated and 50% effaced.
