brown discharge

my period was due july 7th never got it i was a little worried but maybe once a year i miss a period so i thought ok maybe it’s that. my next period is due for august 7th then but today i’ve had a little brown discharge and then i’m about to wipe and look and there’s brown goo hanging down and i wipe it to look at it and there’s a little tiny bit of bright red blood in it. what is going on??? if i get my period usually it’s just straight up red blood no brownish discharge. help!
