Amniotic fluid at 40 weeks

I think my water just broke but I'm not sure of it. I felt it wet down there but I just left it to be extra discharge. I went to go pee recently and all I saw were my panties wet and I know for a fact that I didn't pee myself. It had like a light brownish color to it as well. I'm putting a pad there to see if I am leaking fluid but I don't think it would be that much fluid since I don't have a lot fluid since my fluids are borderline low. Would fluid still leak if I'm laying down or should I stand up, walking around? And I'm not feeling any cramping or discomfort.
