3dpo implantation???

I track my cycle with OPKs and it has been very very consistent. I’m positive that I ovulated on Saturday but tonight (3dpo) I had this super tiny pink spot when I wiped. Could this be the start of implantation or maybe left over spotting from ovulation? I normally don’t spot when ovulating, but just can’t explain this 🤷🏼‍♀️
