Wet underwear?

Erika
I'm 35+1, for the past few days I've been having wet underwear. It doesn't seem like discharge and it soaks through my underwear. I noticed it probably about 2 days ago. It doesn't smell like urine or anything. Is this discharge? Does discharge turn watery? I haven't really had this my whole pregnancy. I feel pressure down low and my vag was throbbing a bit when I go to pee. It doesn't hurt, it just feels like pressure. Anyone else experience this? Thinking of calling L&D
