Implantation or random spotting?

Addrrr • 👼🏻👶🏻👼🏻. Trying for baby #2

Yesterday was 8DPO. Had some dark red in my panties and then just had light pink when I wiped after that. Nothing since last night: my cycle is usually 24-27 days. Yesterday was cycle day 20 and I have never had random spotting in my life. But I did have a MC in July, this will be third cycle coming. Thoughts?
