Can I do anything about it?

May be tmi... Okay, I know (or at least it seems like) vaginal discharge is, okay? I know if it's weird it's bad, but it hasn't changed a lot ever, I have always had it a lot. However, I'm sick of it! It's not usually too bad, but from time to time it's so much that it feels almost like the start of my period, and its horrible to deal with. It hoestly feels like I've wet my pants or something, and though I know it won't  bleed through like blood, it still worries me. I'm 17 and a virgin, so I don't see a gynecologist or anything, so I don't really know about this, so I'm just asking y'all: if you get it like this, how do you deal with it/control? Or /can/ you?
