what where your signs of labor??

i’m 38 weeks and iv been feeling very off the past few days and i have abunch of things going on like diarrhea, nausea, contractions that feel like tightening, back pains, legs and pelvic pains. i’m not sure if any of these are a sign of labor, my o.b is closed for the weekend and i dident get the chance to pay my phone bill so i can’t call anyways, if i have an emergency or major concern i’ll have to to go up to the hospital. i’m just curious as to what everyone’s signs of labor where? even if they were different with all your kids, explain please.
