Pre labor?

What were your pre labor signs if you had any? Right now I'm 37 weeks and 2 days pregnant. I've been having back pain that pulsates and menstral cramps and I've been having diarrhea for the past couple of days and since yesterday I've been extremely fatigued and tired. I've been a lot more moody lately too. I'm a ftm and wondering what others have experienced. I know I'm 1cm and my cervix is soft and I've been like this since monday. I haven't been checked since then because I was checked by a nurse at the hospital and they had to change my appointment for the week to this coming up Tuesday. Anyone else have the same symptoms as me? Or anymore? Thanks
