I was wondering what would cause uncontrollable vaginal itch-pregnant or not, with no discharge or smell, and no antibiotics taken. ?

See an OB/GYN: This may be a yeast infection, but without seeing you there is no way to diagnose over the internet. Hope you get this worked out soon.

Vaginal itch: If you are using tampons you may be allergic to them.

Vaginal itching: Sometimes discharge isn't apparent with a yeast infection. A yeast infection can develop even if antibiotics have not been used. It is one possibility.

Let me explain: Although vaginal itching is the hallmark of yeast infections and other vaginal infections (including stds, itching in the vagina and vulvar areas has multiple causes. Vaginal itching can also arise due to chemical irritants that may be found in detergents or soaps, douches and vaginal creams, toilet paper, bath products, feminine hygiene products, and vaginal contraceptive.
