IB maybe?

So yesterday when I went to the bathroom, I noticed a little small thin line, probably about an inch long of orange/red/whitish discharge, more of maybe copper tone on my white undies. It hasn’t shown up anymore than that one bathroom trip. My cycles are between 28-31 days, from the app, expected AF is 6 days away from yesterday and I would’ve been 8dpo if I actually ovulated at the right time. Could this be a sign of implantation? Not holding my breath for it but I just never experienced that kind of discharge before so just looking to see who has had similar experiences :)
