Went to the hospital tn to get checked after thinking my water was leaking. My ob told me to go in and get monitored, where i was told my water didnt break but i am having contractions every 5 minutes and cant feel them at all!

Is this a sign of early labor? And how long could it last? Im currently 37+1
