Pre term labor?? Almost 32 weeks.

Kiarra

Has anyone experienced pre term labor? I woke up with really bad back pain and also stomach cramps, I went to the washroom and had diarrhea so I thought maybe it was something I ate and would feel better. My back pain is constant and I've made 3 more trips to the washroom plus I am also very fatigued which is also strange because I slept well last night. So my question.. what should I do? Are these signs of labor?
