How do you know when your water breaks?

I have been told that your water can break in 3 different ways: 1) on it's own in a sudden gush. 2) on it's own in a slow trickle. 3) or the doctor does it at the hospital for you. I obviously know it broke with 1) and 3). But if it breaks and it's a slow trickle, how do you know it broke? I know I'm constantly (sorry if this is tmi) wetting myself, so how do I tell the difference between wetting myself or my water broke in a slow trickle?
