weird discharge tmi pic

Bekah • 27 and married, mom of a 5 year old son, and a 1 year old girl, soon to be mommy of sweet baby number 3!
What is this?! I'm 36.2 with baby number 3. I've lost tons of mucus over the past few weeks and have been having awful contractions every 5 minutes with cramping  for a week, cervix not changing, been at a 2 for 6 weeks.
