Early water breaking?

Im currently 28 weeks 1 day pregnant. I was sitting on the lounge and i felt this gush of fluid warm as if i pissed my pants but i couldnt stop it coming out. It went on for about 20-30 seconds then i stood up to go to the loo and my lounge was wet and the fluid was coming out of my pants and running down my legs. I got to the loo took my pants off and my panty liner was absolutely soaked through. By the time i got my pants off while sitting on the loo the fluid had stopped leaking and i was able to wipe myself and change pants. It didnt smell like urine. It had a musky sex like smell. Since then ive had no other loss of fluid and only very slight cramps. My question is has anyones waters broken early and after a minute or two suddenly stopped flowing?
