Contractions, water gush, 2cm dilated

Mandy • I am 34 pregnant w my second. A baby boy. My daughter, who is 4, was born a preemie and thus I'm a NICU Mom.
I've been the the hospital three days ago due to contractions.
They were irregular. Told I was 1.5 dialated
Yesterday at the doctor I was 2cm dialated. 
I am 35 weeks 3 days. 
So my concern is this morning after being up for a while and after using the bathroom. About ten mins later I had a gush of fluid that ran down my leg. Not sure if my water broke. 
If it did I assume more liquid will come out. Should I just keep an eye out?
