Implantation Bleeding or start of period

I need help. Has anyone ever experienced implantation bleeding? If so, what was some symptoms you had? My period is supposed to start in 7 days on Nov. 13th. I went to the bathroom earlier today and wiped very light pink size of a dime drop of blood. I've went to the bathroom 2 more times since and same thing. I'm having mild cramping but nothing extreme. I ovulated around 12 days ago. Does this sound like implantation or a week early period?
