Anyone have something like this happen to them?

I'll be 38 weeks tomorrow. I have been contracting regularly, but nothing too worry about, for the past 3 days. I got up to pee in the middle of the night and it was like flood gates opened. I never pee a whole lot because I have issues but since that gush I haven't had any contractions and I don't recall her moving much, if at all. I have an OB appointment in a few hours. I guess I'm wondering if anyone has had steady contractions for days and then they just come to a dead halt.
