I have experienced a bad odor for the past month. It is bad enough that my husband and I stop having intercourse and hop in the shower :(. My periods come regularly, well regular for me. They last 7 to 8 days but this last one laster 2 and a half days following with a bad brown discharge. It's a brown/blackish color. I'm really worried I have no kind of pain other than discomfort during intercourse. Pleas help!
