Is this implantation bleeding??

AF was due today but the only thing that has happened so far is this rusty colored discharge when I wiped?? Every time my period starts, bright red blood comes out when I pee and when I wipe so this is very unusual. I am technically 13dpo today and I’ve had cramping and sore breasts for about 4 days now. I was expecting AF because i am very regular but this is all that’s happened so far.
