Cervical mucus question! TMI?

Hi ladies!

I am currently 5dpo (had a blazing positive opk 7 days ago, BD both days prior to it), and currently have what looks like EWCM. I know it's not from ovulation, but what else could it be? Is this possibly from fertilization/implantation? I also had the same thing 2 days ago. There is a significant amount today when I wipe.

Thanks for any input! I'm not giving symptoms too much significance, because we've been trying for 6 months now, but this is the first month I've had this type of mucus outside of my fertile window.
