I'm 18 years old and my period started when I was 15. Ever since it started, every month a couple of days before my period, I start to get a weird smell. Not fishy like a yeast infection, but kind of like the smell you'd get if you let a pad on to long. The smell dosn't go away until a couple of days after my period is gone. I don't understand why I get this smell, I have really good hygene. I get a shower and it doesn't get any better. I can't use any sort of vaginal douche because I am extremely sensitive to that stuff. I'm on birth control pills (because I bleed really heavy, but I'm a virgin), but I don't think they would cause it. Is it normal to smell weird down there during this time of month?
