Af or implantation?

Jamie • 👨‍👩‍👦🤱🤰#2💍💙💚

I have 3 days till my period and I haven't had any symptoms. Tonight (5 minutes ago) I went to the bathroom and had light bleeding. Was only there when I wiped not in urine. I've never experienced this and af always on time. I don't feel any cramps, only thing i feel is little fatigued. Could this be implantation bleeding or af?
