TMI! Diarrhea sign labor is near?

Kaitlyn • Mommy of 2: Addyson Rose 03/27/18, baby # 2 due Dec 2019

So for two days now I have had terrible diarrhea. It mainly hits me in the middle of the night/early morning. I have been extremely constipated my entire pregnancy until now. I’m 35 +3 now. I went to l&d at 34 +3 having contractions every 4-5 mins and they stopped labor. Could this be a sign labor is near? I go to the doctor in the morning just wonder what everyone else thinks!
