Super late period and spotting? Help!

My last period started on November 4th and ran the typical 5 days and was a normal period. Since then I haven’t had my period and have had all negative tests.

Sunday afternoon I started spotting light pink mixed with cm when I wiped. The spotting has continued everyday this week and has always been light pink, light brown, or a watery red. A few times there were small spots on the panty liner but it has mostly been when I wiped. I took a test yesterday and thought I had a vvfl but it must have been an indent because both tests today were stark white BFNs.

Does anyone have any idea what is happening? I have an appointment with my PCP but won’t get in to see her for another week and a half.
