watery discharge

So the past 2 weeks iv had watery discharge. Like watery with alittle white in it. Which that's why I haven't done to the hospital because I'm thinking it's just discharge not my water. It scares me alittle because with my last pregnancy that's how I went into labor, my water started leaking and maybe 2 hours later I started having contractions... anyone else having this? Iv asked my doc and she seemed so confused....
