What is this? TMI AHEAD!!

Hillary
Uh, is this my mucus plug? 
33+4, been having inconsistent contractions all night, and have been really stressed the past 24-48 hours. 
This is baby #2 and I honestly don't remember what it looks like, it was super sticky and long, and smelled weird lol (sorry, I warned you tmi) No spotting though. Help!
