Am I still a virgin if I had dry sex with my boyfriend and later bled from my vagina for a couple of days?

Maybe you should make sure to use a condom or some sort of protection from getting pregnant and std's in the future if you are thinking about having sex. Getting pregnant or diseases is not something to play around with. Also, I'm kind of concerned about how much you know about sex because it sounds like you need to become a bit more informed before getting involved in something as profound and intimate as sexual intercourse at your age. Sex is not something to do. There are things you need to know about it and the consequences of it, so I would be more careful in the future and really think about what you're doing before just having sex for the sake of having sex or for the sake of feeling better about yourself because you had sex.

If dry sex means penetration without the aid of KY then you could be pregnant and yes you're not a virgin. If dry sex means with your clothes on, then no and you're still a virgin.
Idon't know your version of dry sex.

that blood was your period!
girls don't bleed for days after sex and dry sex isn't sex at all so of course you are a virgin they only way you can lose your virginity is if put his penis in your vagina which you don't do in dry sex
