Could It Mean That Something’s Off? Yes
Often, yeast infections don’t have any scent at all, and so you’ll realize that you have them from their other symptoms (thick white discharge and itchiness). But in some cases, your yeastified bits will emit a faint bread-like odor, one that can smell slightly musty. Smell will never be your only symptom with a yeast infection, but it can help you distinguish it from bacterial vaginosis or other infections that will similarly irritate your vagina.
