Normal Discharge vs. Amniotic Fluid

Danielle • Mommy to a precious little boy born 12/17/15 and full time working mom! I love my little family!
I'm 16 weeks today and all day I've had lots of clear, wet discharge. It's not thick and sticky like it has been in the past. Doesn't have a strong smell. Maybe just a little musty? I'm so terrified of an amniotic fluid leak. I called me OB but they haven't called back yet.  Has anyone else experienced this?
