TMI ❗ BAD diarrhea at 35 weeks?

TMI ❗ but has anyone had really bad diarrhea later in pregnancy. I'm 35 weeks and everytime I go to bathroom to pee I end up having diarrhea like everytime I use the bathroom. I've been drinking plenty of fluids including Gatorade but I had contractions 2 weeks ago and they had to stop them due to being 6 mins apart. Then again a week later. Plus I've been feeling her low low like sometimes I feel her as low as in my butt area weird I know. But this is my second pregnancy as well. Been having contractions today but aren't constantly. Like I had maybe 4 of them so far today very spaced out. Not Braxton Hicks as I've been through contractions before.
