What were people signs of preterm labor?

Alexis

I am 32 weeks. I’ve never actually been in labor. I’ve always been induced but dude I don’t feel right. I didn’t sleep last night. I been having cramps/contractions all day. I keep pooping. I know tmi. My back hurts and I keep having shooting pain in my cervix that literally knocks me down. The contractions or whatever are not constant and I’ve had no leaking so idk what’s going on.
