Implantation bleeding??? 8 DPO ... please help me figure this out!

Fa

I’m at 8 dpo today. Just wiped after going to the bathroom and saw this... bright red blood! Tested with SMU this morning and it was negative. My period is due on the 26th according to this app. I’m at CD 30. I ovulated really late this cycle at CD 22. Usually a 30 to 32 day cycle. I have PCOS. Please tell me what you think!!
