Delayed period after fingering?

Okay so I am late, a few days ago my boyfriend fingered my really rough and I had brown spotting afterwards, went away though. Still haven't got my period, I am a virgin. But today I got a creamy, light brown discharge? Could that be the start of my period or could it be a cut inside or anyhting else? We are both virgins so Wouldn't be a sti/std :\ please help out pretty paranoid xx
