Discharge

Ash
Hey ladies. I keep having small amounts of white discharge whenever I go to the bathroom I see it on my panties. And my underwear are kind of wet like I held my pee too long but I know I didn't. The spot is about half the size of a dollar bill. Anyone know what's going on? Haven't had a period since Halloween last year and whenever I take a hpt it seems to be negative. Haven't had blood drawn for pregnancy yet
