I've been looking at the symptoms of a yeast infection and I don't experience all of them. I've noticed a frequent vaginal discharge and an unpleasant odor, but I don't have any itching or irritations. This has been going on for quite a while. There hasn't been a day in which I haven't found discharge on my underwear or noticed an odor.
I've also wondered if it could be bacteria vaginosis, but the symptoms seem similar to those of yeast infections.
