Is my water leaking or is it discharge?

Kayla

I'm 28 weeks pregnant and last night and all today ive been feeling I have to be pee really bad and I go to the restroom and I dont have to pee at all or barely anything and when I go to lay down in bed I'll feel like I peed myself a little and I just ignore it and and I have this wet spot in my crotch area in my underwear that keeps getting bigger every time I go to pee. Could this be my water leaking or discharge?
