CM Check (Warning: Tmi pic?)

So the last day of my period was Friday the 5th & afterwards it seemed like I still had quite a bit of dark brown stuff whenever I'd wipe there for a few days. No matter how much I cleaned there was more. It was like a very very light period but the wrong color entirely. Today I checked my cervical mucous and this was what I found. I've never checked my cm before, but from what I can tell from online- it should be white or clear? I've had a bit of a cold so idk if that could have anything to do with it. I honestly am very new to checking my reproductive health and just need some advice. The two issues may have nothing to do with one another. I just don't know.
