Discharge or leaking water?

People who have done this before: How can you tell the difference between heavy third trimester discharge and your water leaking? I’m 33 weeks right now and I’m mildly concerned. I went swimming earlier tonight and felt a little gush, but it could have just been water trapped between my legs. Since I got home, my undies are just damper than usual.
