Implantation bleeding or early AF!? 🤷🏼‍♀️

I am currently approx 11dpo and AF is due in 3 days. I took a hpt 2 days ago and swore there was a VVVVVVVFL but just went to the toilet and had the tinniest bit of light pink blood when i wiped. Is it too late for implantation bleeding? Is AF just coming early? 😩
