Symptoms of a yeast infection are hard to misread. There will be white
discharge that looks like cottage cheese, and the itching around vagina will be much more than just a little Also, they will last till you treat them.
Odorless white discharge could be normal vaginal secretions. I'd look out for discharge that doesn't clear up on it's own, is like cottage cheese, or green or something, odor, and itchiness. if not, it seems to be normal.
