Tmi sorry.. Period???

Yesterday my af was due but only got brown discharge and today nothing... I think I ovulated around june 29 (because of the ewcm that I got) this never happend to me when my period is due I bleed from day 1 and at the end I get that brown discharge but not at the start.. I tested 3 days before af was due and it was negative but today I have  no cramps and no blood 😕
