Well every woman is different, and everything is possible: some bleed, some don't when they lose their virginity. Bleeding isn't something 100% indicator of losing virginity. Some girls can lose their virginity even when dancing, riding horses and other cases they bleed thinking that is their period and then when having first sex (of course) not bleeding. Or not bleeding at all. You can ask that a doctor or you could search the internet, it's written there. I personally did not bleed when I lost my virginity. During the whole intercourse I had pains but I didn't bleed at all, then that night I noticed a tiny spot on my underwear that was really hard to notice. I had a friend (male) who told me that his girlfriend didn't bleed when he took her virginity. Many people say that some girls don't bleed simply because their partners' penis is too small, but who knows if that's true as well, I personally don't think so. Also many people say that if the girl didn't had bleedings then she wasn't virgin as she said, which I know for sure that isn't true that (even though I think that there are cases when some girls can lie). I just want to say that not bleeding is not an accurate indicator of not being virgin. You also may hear other women who can say that they were not bleeding when losing their virginity. About other signs or symptoms that can be a proof of virginity I don't know what to say, maybe there are some but I don't know them. As said, ask a doctor. good luck
