please help!

I'm freaking out a little here and it's probably nothing; anyway my period is almost a week late now and i thought i started today but it's just this brown discharge, it's like my vagina decided to become a poop factory instead of a baby factory! Worried i might be broken... And no, there is no chance i can be pregnant. If you can help i'd be sooo grateful! Thank you
P. S. Sorry if this is gross...
