Im 15, sexually active for about 4 months. And recently have had some itching on one side of my vagina and a white, clumpy, odorless discharge... I want to make sure this isn't more then a yeast infection or a reaction to me changing soaps.

It could be a reaction or a yeast infection or just a change in your body's ph level due to you becoming sexually active. It could also be an sti so the best thing to do is make an appointment at your local gu clinic. I would also advise your partner go too. Its probably nothing but it's best to get it checked out and at least it will put your mind at rest.
