Labor ???

Ok ladies im 36+2 weeks . Ive been in early labor for about a week now having more frequent BH and inconsistent contractions. Last Wednesday i was at L&D and i was just a fingertip dilated and not thinned at all i had an ob appointment that morning and i was at a 2 and 60% thinned. Well the last 2 days the pelvic pressure and contractions seem to be getting stronger and more frequent. But today they seem to be coming a little closer but the pain is in my lower back and wraps around to the center of my belly. And its happening about every 3-4 mins for about 45 secs could these actually be contractions?? I also have a uti so i dont know if that has anything to do with it ??
