Underwear always wet since first trimester

Brianna
Im 26/3 weeks pregnant and my underwear is always wet like I have to change underwear 2 or 3 times a day. I've gone to labor a delivery like 3 times because I have a huge fear of leaking fluid. But it's come back negative every time. And I've had this since like 14 weeks it's just gotten worse since then. It's like a watery discharge. If it's not fluid then what is it? I'm so tired of being worried about my fluid every day. Anyone else have this problem?
