Really???!!?? How far along are you? That sounds crash y that they sent you home!!! I would go back and tell them your not leaving!!! You wouldn't want to risk having the baby in the car ride back to the hospital ( not saying you will but you never knots how fast it could happen( and your already half way there!!!!
That's what I thought...but they sent me home because my contractions are not regular enough. :(
5cm, usually they will keep you or send you to L&D.
