What am I leaking...?

I don’t know if I’m leaking amniotic fluid or just discharge? It’s clear, watery, has a slight stickiness to it, and no smell. Doesn’t smell like urine. Not hot or warm.

It’s not constant but it is frequent...I’d say once every hour I’ll have a few drips. I’m 20 weeks. I have a doctors appt next week, but wondering if I should be concerned.
