Leaking

Okay, I am 36 weeks and 3 days. I have what seems to be a watery, clear (sometimes white) discharge. My question is, I don't know if it's just urine due to being pregnant. I can feel it come in gushes. But not like a gush down my leg. And it's never enough to get my pants wet, but it will soak my underwear. It doesn't have a smell that I can tell. And it happens quite often. Even right after going to the bathroom. Just wondering if it's urine or if it could be amniotic fluid.
