Could delivery be here soon?!

Im 37w 4d TMI but ive been having trouble going number two for a couple of days. Tonight I had HORRIBLE pains and urge to go. Finally got the hard part out and after it came out it was literally diarrhea and a ton of it. Ive never had a poop like that in my life! It was like tar almost 😩 I had two bathroom breaks like that right after each other. Also I lost a good part of my plug. Could this mean labor is soon?! TIA!!! Sorry for tmi
