Woke up to wet shorts? Not sure if it's a leak or water breaking? Pls help

Lindsay
Hi ladies I am 39+4. I woke up this morning and my shorts were wet. Idk if it could be end of pregnancy discharge, a leak, or even my water breaking. But I doubt it because it wasn't like a waterfall- they were just wet. I am going to get checked at the hospital but I really don't want to feel like the boy who cried wolf and get sent home! Please share any expertise. Thank u!!
