Could this be preterm labor???

I’ve been having what I thought was Braxton Hicks for over two hours now but they are pretty painful and are anywhere from 3-10 minutes apart. I’ve tried switching positions, drinking water, walking etc but nothing helps. After about an hour and a half of these constant “contractions” I started having severe diarrhea which I’ve always heard is an early sign that you’re going into labor or “diarrhea = dilation” I have an appointment early tomorrow morning so do you think I should just wait and see what happens or call right now? I’m 23+1 weeks.
