Why does my vagina have such a bad smell all of a sudden? It's not and STD because I just tested negative last week, the smell came about a week after my period and to me it's a very noticeable smell. I'm thinking maybe it's a yeast infection? I don't know I've never had one. My discharge is cloudy but not clumpy and solid white. I've never had problems like this and I have a gynecologist appointment the 10th.. does anyone know what's up?
