Tmi warning but help

I'm 16 w 2d and every time I go to the restroom and I'm ready to wipe there's like a thick line of discharge or something just hanging down. Its so nasty. Its yellow and not clear. Should I be worried ? Do I get checked out. If it has anything to do with it I have a bladder infection but I doubt it. It doesn't smell bad or no itch. But disgusting.
