Leaking fluid?

Anyone else around 31 weeks and having a hard time deciding if you are leaking fluid or if it’s pee or discharge? Last night I was walking around my house and felt a gush. It wasn’t enough to run down my legs but it got my panties pretty wet. No color and no smell. I really don’t want to go to the ER and them tell me I peed on myself.. I’ve been so paranoid all day
