Sign labor is near?

Okay so this post might be a little TMI so sorry I’m advance about that.

Just a couple days ago I’ve been having bad diarrhea right after I eat anything. I didn’t have a problem with this my whole pregnancy and I am 33 weeks along. I had diarrhea with my first pregnancy right around the time I went into labor but I got it after 38 weeks. They say it CAN be a sign of labor after 37 weeks and if your before 37 weeks and in the 3rd trimester it CAN be a sign of preterm labor. Anyone else have any experiences with this? Only other thing I have going on is contractions here or there but not enough to be extremely concerned and increased vaginal discharge.
