Unsure

Ok, so I thougth I was straight until like a couple of months ago, but I got a big crush on this girl in my drama class, and am now questioning everything. I've never had a crush on a girl before. And now I have a kind-of lowkey soft crush on one of my friends and idk??? I've only told my two closest friends about this. Anyway, enough of my angst, my question is: Should I tell my friends I'm unsure, or wait until I know if I'm straight/bi/pan/etc?
