What are some of the vaginal infections you can get when u are a virgin????

Yesterday my bestfriend told me for the last 3 days she has had like blood like mucus coming from her vagina. She has already had her period it ended on the 14th she said, and she has never done any sexual activities. She said everything else has been normal. So what could be wrong with her??? because I am starting to get curious myself

This is normal. your period will change several times during your whole life believe me. There are alot of vaginal infections that you can get with out being sexually active. There are some that you can get by contact like wiping yourself with a tissue that was air-exsposed to an infection. Girls go through it all just tell her if her discharge becomes another color or ordor that she should take notice of what shes using, in example soap, some are highly sensitive and can cause irritation... down there, make sure she has underwear that are white in the vaginal reigion, also her washing powder can cause irritations, make sure your pads are unscented or hypo-allergic. Being a girl comes with alot of responsibilities and every lesson is worth it..

This might be a long shot, but it could be that a tampon punctured her hymen near the end of her period and that's the tissue being expelled...

It's better to go to the doctor, she may have some kind of tumors developing or something may be wrong in her uterus , No infection (that I know) comes with blood, generally is just itchy and smells bad.
Tell her to make an appointment as soon as possible, she may need blood and urine tests to find out what is really wrong
