For the past couple of days thick brown mucus looking stuff has been leaking out of my vagina. it smells awful and is non-stop. what is this?

Brown = old blood: Irregular periods are one of the most common problems obgyns treat. If this is one time problem it usually resolves on its own. If this is a recurring problem you should be evaluated. Infections & hormonal changes can cause spotting. Brown simply indicates old blood and is normal. The foul may indicate infection. Get tested
