False labor

Kimberly
I'm 36 weeks and 6 days today.
Back was hurting me all morning then around noon my whole stomach started tightening I started timing them and they were 5 minutes apart I went to lunch at 1 pm and called my ob he told me to head to labor and delivery they hooked me up and had me laying down they checked me and I'm not dilated my contractions eased offed and they sent me home :( so no baby today feel like I wasted everyone's time
