Implantation Bleeding? 10DPO

Hello! Yesterday I got some spotting in my underwear. I have never gotten any form of spotting before.. today at midday, I had some light pink-ish spotting among the CM.. But nothing more after that. I’m supposed to have my period in 4 days.. Do you guys think that it’s my period that is early? I’m at CD27 now, and my last cycle lasted for 34 days... could it be an implantable bleeding?🙊💕
