Diarrhea before labor?

So I have read about women getting diarrhea before going into labor and I’m wondering how true that is. I’m only 35+2, so I don’t really want it to happen soon, but of course I’m fine with getting the physical relief. The past week my nausea has come back, my hips are incredibly sore, hot flashes, and intense headaches. I didn’t get any of this with my son, so I’m just nervous it could mean something. I’m hoping to hear that people had the same thing happen and labor was still a couple weeks away.
