TMI question

Okay I know this is super TMI but I am curious ...

This is my second pregnancy. I am 32 weeks.

I know we have a lot of weird discharge and such. Mine seems normal but the last few weeks (maybe not that long) I will be standing and a gush of warm discharge will come out and/or I will have a lot of “air” come out “down there” along with liquid.

Does this sound normal or just regular discharge? Curious if it is amniotic or not.

Edit to add I see my OB Thursday but curious what people think ...
