HELP! Can your water break and you not notice??

 I'm nearly 38 weeks. I'm sitting at a desk doing some work. My backpack is behind me, and there is a water bottle in my back pack. Suddenly  I realize my shorts are soaked and they soaked a little bit of my backpack as well. My first thought is it's the water bottle bc the wetness is mostly in the back and my butt although my front is soaked too just not as much and it could've been the way I was sitting. 
But after looking at the water bottle there is no hole in it, it's not leaking no matter how many ways I turn it and it doesn't seem to be any less full than it was when I put it in How could I just not notice until my shorts are soaked. It left a little puddle on the seat. but nothing is leaking currently. Since I am currently on campus and not at home I don't have a change of clothes or a pad. I put some toilet paper in my underwear and am going to see if it soaks through. Just confused because the water bottle didn't have a leak in it but I also don't feel myself leaking.
