Implantation bleed or period?

It’s been two weeks since I had sex yes he did cum inside of me. I’ve been having brown & pink blood since yesterday very light only when I wipe but can’t work out if it’s implantation or my period?

Last night I woke up 1am my hair and top was drenched with sweat (I never sweat in the night either) then woke up at 3am freezing cold

Also I done two test yesterday which were both negative.
