Water break but no contractions??

Help!! I was lying on the couch all night and there were little cracking/popping noises coming from my belly. I just brushed them off as baby's joints. Anyways. I got up to go lie down in bed and as I'm standing at my dresser, I felt pressure and then a small gush of liquid ran down my leg. It was clear and didn't smell like urine. 
BUT I haven't had any contractions and it was only a small gush. I just started having some sciatic pain, but nothing intense. Was this my water?
