Thanks for query,
Are you fingered for first time but have you enjoyed sex for the first time.?If yes then this bleeding is from break of Hymen
It is a normal in virgin girls that during first sex act or first finger act hymen breaks.So nothing to worry.
If you have enjoyed sex earlier but fingered for first time that this act may be considered cause by injury
inside your vaginal wall.So you may consult your doctor if you have last bleding for few more days otherwise it may stop by its own.
