Period or Possibly Pregnant?

So gals, I'm already a week late with my period, but when I go to wipe it's a brownish color. The first two days of being late, when I had gone to wipe it was a slight pink. This color showed up again around the 4th - 5th day. This only happens when I go to wipe because I used a pad just in case of anything and nothing shows on the pad. When I wipe it's not a lot that shows just a little. I have no period symptoms nor pregnancy symptoms. Any thoughts on what this could possibly be? Has this happened to any of y'all ladies?
