AF? or IMPLANTATION? pls read

I am 8 DPO, depo expired in April. I had a period a week and half ago & started vitex during it. ( it was my first period since coming of depo ) well this bleeding started at 6 DPO. its never pink/red only when I wipe! its not heavy at all. Anyways do yall think this is implantation? or my period?? Glow says my period isn’t supposed to start until July 12th. I don’t know if this is from Vitex or what? ANY info or input is greatly appreciated!! 😊 Thank you ladies.
