Help! Implantation Bleeding or signs of AF?

LA

Hi Ladies! I am currently 9 DPO. 5 DPO I had brown discharge 2-3 days in a row. Today (day 9) I noticed after using restroom pink bleeding as I wiped (sorry TMI), it was minimal. My period is due in 5-6 days. Is this a sign my cycle is coming or implantation? If implantation is it normal to have brown discharge day 5, like I did? Thank you in advance!
