Fluid, pee or discharge tmi maybe

33 weeks tomorrow... So a little bit ago after I peed I got up and walked into the other room felt like a gush of wetness and ended up soaking my undies, but not through my pants or down legs.. Changed, since then have felt wet and there is a tiny but thay looks like it's leaked out but not much... I never had this happen with my first pregnancy so I don't know what's going on...
