Implantation bleeding? 8dpo

So I wiped and there was a tiny pinhead of blood tiny i barley even could see it. Was rusty looking then I read online some ppl check with a qtip so I did lightly and got this. I am 8dpo according to glow my ovulation day was july 20th anyway does this look like implantation bleeding? This is all there was. There is no more now. It went away.
