The bad news: Not all vaginal infections are yeast infections -- it could be something way worse. Great.
The good news (well as good as it's going to get): Fem-V ($7.99) has created a pantyliner yeast infection test that only takes 10 minutes. If the indicator strip on the pantyliner has a blue or green color stain you should consult your health care provider as your vaginal symptoms may need a doctor's attention. If the indicator strip remains yellow or fades back to yellow your symptoms are more likely caused by a yeast infection and you may choose to use an over-the-counter anti-fungal treatment.
