Could this be contractions?

Or just food not agreeing with me Lol. So I'll be 39 weeks tomorrow, last 3 visits have been no change 1 cm and thick cervix. My next appt is Mon.but the last two days I've had bad indigestion, acid reflux, my tummy has been making all kinds of noises, and had kinda this weird crampy feeling in my tummy, not so much lower area just around belly button, and not solid but not dirreah stool, and kinda a blah feeling. But the weirdest is my tummy it feels tight and crampy but idk if it could just be what I'm eating? Any ideas? I've yet to have a BH contact. Or anything..
