Water maybe has broke??!

It’s currently 4 in the morning and I woke up out of my sleep for some reason. I felt wet down there almost like I maybe have peed so I felt it and my shorts, panties, and couch was wet.... it has a weird smell it’s not really strong it just has this weird smell to it. Never had anything like this happen. Could this be my water? I feel crampy and back hurts but I really don’t want to waste a trip to hospital.
