Is this implantation bleeding?

Been having this for 2 days now, not enough to flow onto a pad, it's only really there when I wipe, and sometimes not even as much as in the photo.

Around time of period due, but usually I'd be full flow by now!

Did a test this morning and bfn with a first response. I know even if it is IB, I may have to wait a few more days for a test to be positive. I dont have any cramps that I'd usually have when getting my period either.
