May be Tmi but could use some help

AF usually shows up bright and early, but today it's brown discharge with minuscule spots of red.

I should add I have cramping and back aches. Idk what to think. Is my period here or do I still have a chance? My hopes are pretty much gone but I'm obsessing and can't stop.

Any one else had similar discharge upon getting their BFP? Or do I just need to start planning for next month?
