Water broke/leak?? Maybe??

I've had something similar in the late second trimester but it was less of an amount. I just woke up (3:30 am) and my pants had a bunch of water I guess on them. I'm not sure what it is and it doesn't really have any sort of smell or anything. I don't feel anything so I'm assuming it's just a lot of watery discharge for now? No signs of labor so far, just woke up in a small puddle of water. 
Edit: I'm 37 weeks and 5 days, and I peed after I got up, my urine was yellow, the water was on my white sheets and was clear and smelled nothing like urine or anything at all if that helps. I also have no way of getting to the hospital at the moment.
