You need to be seen by a doctor it could be a number of things such as a yeast infection to an STD if you have been sexually active... You shouldn't worry about your mom knowing you should be more concerned about taking care of your health...again it's best that you be seen by a doctor in order to properly treat this issue.. Best of luck to you!
You need to go to a doctor asap. Maybe your doctor will be discreet about it if you talk to them privately. But either way - go soon and do not have sex with anyone until you figure it out. Good luck!
