After your period, it should smell clean and normal, if it doesnt you have problems. If it smells like bacon lol, you probably have Pelvic inflammetry disease, which can be caused by bacteria, but is easily treated by antibiotics. If is smells like gone off milk and you have any itching or creamy discharge, you have Thrush, basically a yeast overgrowth, which can be treated orally or with pessaries, If the smell is really, really nasty, you could have gonnehrea think thats how you spell it, lol. Again treated by antibiotics. Thrush and the other with the G are very contagious, sexually transmitted, so I suggest you take a visit to your sexual health clinic at the hospital and put your mind at rest. It is very discreet and you will be treated quickly, usually no appointment. But for the time being use condoms, dont sleep around, and dont worry, hope this helps.
