Did my water break??

I woke up and felt wet down there so I felt it and sure enough there was a lot of liquid. It's very thin and doesn't have a smell to it but I thought when your water broke it's supposed to be a lot? I read a forum online and a lot of girls didn't have a gush, they woke up and to being a little wet and ended up having no fluid left when they went in. I had a false alarm before so I'm just wondering. I'm 38 weeks and have not had any contractions at all. I woke up in the middle of the night because I couldn't sleep and he was moving a lot and I felt I'm sharp pain but that was it. My husband said my belly felt like deflated to? Should I go in or wait and see if when i change my underwear they get wet again?
