Coughed and suddenly wet!

Im 27+3 and I coughed and I felt a gush of fluid. I've cleaned my hands in antibacterial soap and placed a finger inside and gave it a good wiggle, it was wet but if I rubbed my fingers together it would leave little white pools of fluid. I felt wet yesterday too and today. Due to see my doctor on Tuesday for a scan too but this doesn't sound like waters does it? More like pee?
