so i'm fifteen, virgin, and started my period 2 years ago. i have vaginal discharge.. its white, kind of gooey, and smells weird. whenever im laying down.. i feel like i have to pee and if i dont pee i get a sharp pain in me right lower back around the kidney. but when i do pee.. nothing comes out. also, i have another problem.. whenever im at volleyball.. my vagina smells weird and i can smell it when i just sit down, it is a very strong odor also, im too afraid to go to the doctor.. i feel embarrased.
