Yellow liquid?!

Hi guys today I finally felt better from a recent cold, I had pt today so I sweat a lot..and in my 3rd looked like my nose dripped piss all over my test and the table..I checked the consistency of it and it wasn’t even a snotty-like was like water and looked exactly like did dry somewhat red I’m concerned maybe it was a nosebleed? Although I never get those because I’m used to the pressure in my state
