And it starting to make me short of breath Should i Go see a doctor and tell my parents who are still worriedd sick about me. Any info on what this could possible be please help out if you can.

yellow usually means you are getting over an illness and its your body bringing it up and out. Try cupping your hand and hitting your chest with it. it might help bring it it up. If it lasts mor than a few days i would go see a doctor. If you notice it changing color, like red or green, definitly go see a doctor.
