My period is not due until next week but after being fingered quite hard i bled a lot. it's slowed down now, but is it possible my period is early?

Maybe: Either that or you got a small laceration; if u never had intercourse or had that experience u may have ruptured your hymeneal membrane. See if ur period comes. Small lacerations of the vagina heal quickly if that was it.

Yes: But it sounds like your partner needs to go a bit easier on you. A simple scratch with a fingernail could cause bleeding and a vaginal infection.
