To go in or to not go in

37 weeks.. I’ve been having contractions consistently for about a week now, they don’t hurt but they’re there and in my back. The baby’s head is grinding on my pelvic bone, I’ve been feeling the need to go poop but can’t. He’s constantly moving, hasn’t stopped since last night around 730 pm. I was dilated to a 2 at my last appointment. This is my third baby, I just feel so confused and clueless about this whole thing. But I am tired of being in pain constantly. Any ideas?
