Too much fluid around baby?

Has this ever happened to anyone else?

I was told baby has to much fluid around him but we both keep passing the NST . I am 36 weeks 4 days

She said he’s a big baby also, so bad me redo the gestational diabetes test and we are waiting for that.

I feel mostly fine just short of breath sometimes was told it’s from the fluid.

I’m just a little worked up.
