It is really important for women to recognize their own scent so they know what is normal for them and can recognize any changes in their bodies - just like doing breast self-exams. Perhaps you may perceive that your normal vaginal scent is a problem - but it may just be your normal scent.
 

The most common cause is vaginal bacterial overgrowth known as bacterial vaginosis, which has a "fishy" or "musty" smell. "Fishy" smells can also result from vaginal infections, such as trichomonas vaginalis. The vagina could also smell "yeasty" because of vaginal yeast overgrowths - yeast infection.

Synthetic underwear, pantyhose, tights, and Spandex exercise clothes do not allow air to circulate around the vulva (the outer lips of the vagina). A moist environment promotes overgrowths of normal skin bacteria that could cause vaginal odor.

A physical exam by a health care provider can determine whether or not the odor is being caused by something that is treatable with a medication, such as for bacterial vaginosis, trichomonas, and yeast.

So, when in doubt, it’s safest to contact your doctor’s office to discuss the changes you are experiencing.
