Girls and women may have brown discharge just before, during, or right after their period. Most of the time it’s normal and not a cause for concern. The brown color means that there is slow bleeding from your uterus, unlike when it’s bright red and flowing faster. Brown blood is often a smudge or spotting. If the discharge has a bad odor, you have itching, lasts longer than a day or so, or comes at a time not related to your normal period, you should make an appointment with your health care provider.
