brown discharge...what does it mean?

i’ve been having a brown colored discharge the last few days but have been 5 days late for my period. i took a pregnancy test which came back negative, plus i’m on birth control, so i’m can’t be pregnant. what else could be the reason i’m late/having brown discharge?
