could this be implantion bleeding?

Hi Ladies. I am currently 8dpo and had this speck of blood when I wiped. I had something similar at around 5dpo but with discharge. Could I be implantion bleeding? The last day I've had bad backache and some weird cramps not like menstrual cramps maybe a little lighter.

(bottom picture is not mine found it on Google but it's similar to my situation.)
