Spotting instead of Period.

Cycle day 42 and I have been spotting brown and pink, only when I wipe, for 4 days. I took two tests on cycle day 29 and 35, both negative.

The only time I ever spot is 2-3 days after my period has ENDED. I’m gonna test in the morning, but has anyone had this before BFP? I’ve truly never had spotting before, and I’m super confused about it.

Normal cycle for me is 33-45, but for the last 4 months, it’s been 29-35. And I normally have intense signs of AF approaching. But I’ve had nothing at all.
