Fluids/ leaking

I am 29w+1 . This weekend, part of my mucus plug came out. I called my OBs 24/7 hotline & they told me to just watch for blood or cramping. This morning I went ahead and sent my doctor a message as well just letting them know, and they told me to watch for blood & cramping same as the hotline, but they also told me to watch for leaking fluids or a gush of fluid. Does anyone know what the fluids leaking i need to watch for look like/consistency? I have normal discharge too, and don’t want to mistake leaking fluids for normal discharge & vice versa. The doctors office is already closed so I can’t message them but don’t want to call the emergency hotline and ask them
