Hi and thanks for using the forum.
You are going to have to talk with your doctor about this. It could be something simple like a vaginal infection, but it would need treatment. Don't be worried to discuss things with your doctor- they have heard it all before. If you are sexually active, then you may want to make sure that you don't have an STD. Good luck.
