Have your parents taken you to a dr?? Are you sexually active?? these are questions that need to be addressed. It sounds like a vaginal yeast infection, but you are young and should go see your family physician to start. If you feel comfotable, talk to your mother or another close female adult they may have answers that people here cannot give with limited access over the net. Hope you get the answers you are looking for...
God bless and Good luck,

Whitish sticky stuff, even a lot of it, could be normal for you as it is for a lot of women. Bad smells however are due to bacteria and are not normal. The doctor can prescribe antibiotics that should help. If you've tried everything else that would be the next step. Good luck.
Talk with your mom and have her take you to the dr.
