Leaking *** TMI

Leaking urine or amniotic fluid?

My panties the past week or so have been very wet, when it dries it's kind of brown. I notice more wetness while up and about but it still happens when I am laying down. I don't feel as if I'm urinating.. like I do when I sneeze. Lol. I did a Google search and well it freaked me out. Anyone have any advice?
