IB help


Okay so I'm 9dpo and I've been bleeding for 3 days but ever so lightly. I've not had to use any sanitary products and the bleeding is only visible after I've wiped. My A/F is due on 1st September. Could this be Implantation Bleeding. First pic is 3 days ago (first lot of blood) the second pic was this morning (even less blood than that now)
