Implantation bleeding ?

Pare

Need some advice. The last couple of days I've been getting lower back aches. Today I'm around 9-12 doo (flo app is telling me 12 dpo and pregmom telling me 9dpo) I have a 29-32 day cycle. This morning I went to the bath room and when I wiped I got this (photo). Nothing on my undies or anything just when I wiped. I went back to the bathroom 2 hours later and still nothing there and nothing when I wiped.
