Thanks for the replies
Was probably just discharge, esp if it happened when you sneeze. If it was waters you would be soaked! If you're concerned though, maybe get it checked out.
Happymammie - if it was waters it should continue to trickle - even ever so slightly so you should continue to feel wet. I am sure that mine went the evening before on DS - i.e. like a trickle as I felt for the night like I had pee'd myself ever so slightly. I starting having contractions the next day. Hopefully it wont be long for you now.
