TMI (mucus plug pic)

Maybe mucus plug? Okay so last night I went into L&D because my contractions were strong but they only dilated me about a half a cm in two hrs. So they sent me home. I came home, slept all night. Went to get a mani pedi (contractions and all) and just got home and this came out. Since then, I've been hanging out in my bath tub trying to relax. Do y'all think it's almost time? My doula is on her way, because my contractions are getting a bit more intense. Should I get excited or not quite yet? Btw, way more came out.
