Please help! I have developed a bad smelly discharge which in somewhat brown in color. My periods are normally right about the same...but this month my period was extremely light (like only 1-2days long and without having to wear any pads or tampons)...then i noticed this smell starting. Now its soo bad that i can smell it through my clothes and when standing. Also a couple days ago my vagina lips seemed like they were swollen (and i didnt have sex) but they dont seem swollen now

Please help!!!!
