Tmi what could this mean?

I'm 9 days away from period, at 10 dpo today and this morning after peeing noticed this. What could this be? A friend told me implantation bleeding. I've never experienced ib with my other pregnacies, so don't know what it looks like. I've spotted before but a day or 2 before period but not this far out. Can you tell me your experience with ib?
