You could have a yeast infection. Is there white or yellow discharge? Does it hurt to wipe? Is there itching? These are signs of an infection, which typically starts with mild pain that builds up over days. Those can be treated easily at home, but I'd suggest you see a doctor anyways because it can be difficult to pick up on the symptoms. Also, it could also be a urinary tract infection, which has similar symptoms. If either, you need to get treatment right away. They get worse as time goes on.

So, if you are still having an issue in a day or two, tell one of your parents and go to the doctor. You shouldn't wait weeks and drinking water won't fix it. I wish it did, yeast infections are the worst.
