Implantation Bleeding?

Hello! I’m 8dpo and noticed this when I wiped. I’ve been super tired, my chest began aching last night, and I’ve had some light cramping on my right side. I also have a dull ache on the right side of my lower back. I never spot before my period, and I was wondering what you all thought! I’m obviously going to wait to test for another few days, but I just wanted to know if anyone else has experienced this at 8dpo and got a BFP. Thank you!!
