Help weird discharge while being due for period

Hey guys I'm kinda really stressed I'm 3 days late for my period I got like a brown pinkish discharge that's exstremly light like you can just tell there's a colour to it when I wipe,
I'm a virgin and the only sexual thing I do is bascally grinding on each other (dry humping)  and one situation where we tried to do anal but failed do you think I could be pregnant ?
