So three days ago I had unprotected sex with my boyfriend. So Yesterday at school I noticed a foul odor but I wouldn't had guessed it was me because my vagina never actually smelled. When I got home I still noticed the foul odor and I stuck a finger inside, out came white discharge and a foul smell. It doesn't have a fishy smell but it's really strong and unpleasant! Any idea of what it may be?
