GIRLS ONLY!!!! This is really gross just to let you know. Please help someone!!?

Okay so a few days ago I was going pee and when I wiped there was a glob of clear stuff. It had the consistancy of phlegm. It came from my . Once in a while, a little bit comes out now but that's the only time there was a lot of it. Does anyone know what this could be??? I'm 13 1/2 years old. I haven't started my period yet. AND YES, I'm still a virgin (who would be crazy enough to have at 13???????). Please help!!!!!!
