Having contractions and got sent home

Mayra
I went in because I couldn't take the pain of my contractions. They're all over the place... per the contraction monitor at the hospital they're 2 min apart, 3 min apart and 5 min apart. They checked my cervix but since I'm Not dialated I got sent home. Has this Happened to anyone?   
A little background info my original due date was June 12th but per a recent ultrasound baby was measuring bigger so new due date is may 29th.
