Help what?!?

So I’m not supposed to get my period for 3 more days but earlier today I peed and wiped and saw it was a little red so I put a panty liner on and I just went pee again and when I wiped... nothin! The thing is my bf and I haven’t seen each other in a while and tonight was supposed to be steamy wink wink but how come i don’t see anymore red? Can you bleed a little before your period actually comes and am I in the clear for tonight? Or do y’all think it for sure started?
