Could also be discharge or just sweat

Probably urine, my underwear stay wet from urine leaking before I go pee or after..

That's exactly how I feel it's been happening every day for three days now

Could be what previous person said or it could be a bit of urine leakage... Happens to me daily, I don't even realize it or feel it. Wearing panty liners helps but if you are concerned you can call your OB

It could be your water breaking slowly... I would call your OB and ask
