It sounds like a yeast infection, but could also be something else. It's common to get yeast infections from antibiotics, too. I'm prone as well. I wouldn't really take anything over the counter till you get a pelvic exam from your gynecologist. I have no clue about the bleeding issue, but that should get checked as well. also, I usually don't get odors or discharge as well when I get them, too, so at times, I wander if it could be bacterial or something else, but can rule out other things, because I'm not sexually active. This is why I always go to mine, and get Diflucan or something prescribed by a doctor. Take care!
