Am I leaking fluid?

I posted on here last week about leaking fluid.

The swab they did with a speculum was faintly positive but fluid levels around baby were normal.

I went back the next day and nurse swabbed but just manually up my vagina, not using the speculum. It was negative. Also ultrasound showed good fluid levels.

My OB told me in a follow up appointment the next day that if and when my water breaks, it will break and that's that. Nothing can be done to prevent it.

Well the wetness stopped for a few days but was sort of back today and now I just checked my underwear and it is wet... Clear? Am I actually leaking???

I'm freaking out :(

I had my first child at 35+4 due to slow leak so I know it makes my chances higher for PROM
