Yes!
I went to bed at midnight and woke up at 1am feeling like i needed to pee, i got out of bed, walked a few steps across the bedroom, got to the door and i felt and heard a "pop" and there was a small gush and when i looked down there was a constant stream of fluid leaking on to the floor in the hall.
I know for some women they feel they aren't sure if their waters broke or if they peed but in my experience it felt very different. Not only does amniotic fluid have a really distinctive smell, but there was no way of controlling the 'leaking' no matter what i did, and later once i was in established labour, my waters which were still leaking, had a slightly pink tinge to them.
