Due to when I started bleeding the smell of my period put me off, it was an off smell gone wrong.. Has this happened to anyone? What is this caused by?

Is it your tailbone? If it is I had the same problem it could be that your putting too much weight on it and the way your sitting. Do u have big breast? That can be the cause also

Oh I'm sorry wrong answer. Yes that happen to me it's a build up of bacteria its fine just go to your doctor and tell them the smell and they will give you antibiotics it will clear up in a day or two.
