Amniotic Fluid?

so for the past 2 days i’ve been having to wear a pants liner because i’ve been leaking this thin watery discharge, it doesn’t have a smell and it’s clear! I’m 35+4 and i’m scared it may be amniotic fluid. it literally soaks my underwear but only comes out a little at a time. i’ve had an increase in discharge but it’s not the milky white it usually is and it doesn’t smell like pee and i try not to call my doctor unless i have to. has this happened to anyone else?
