37 weeks leaking small bits of fluid?

Cannot tell if it’s pee or natural discharge or amniotic fluid. It’s been several days I’ve just had an access of discharge.

Something new the past week is cramping at night. But I still think it’s early to assume. It could be anything more than normal discharge or mucus plug?

Also no blood, seems to be very thin and watery. About idk 1/4 teaspoon size in my underwear pretty consistently.

Thoughts?
