Brown CM instead of AF

Christine

These were my tests from 5 days ago. I swear I saw a line on both but just chalked it up to be an indent. But now AF is supposed to be here today. Not a sign of her. But I do have light brown CM, only there when I wipe. This has never happened to me before 🤷🏼‍♀️ what do you think guys?? AF or possible BFP underway?
