This may be TMI - I'm wondering if anyone out there has spotted during their cycle, past AF but not during your TWW?

I'm on CD10 and I've been spotting for a couple of days. Normally I have a discharge I'm used to 3-4 days after AF finishes, but I've never had actual spotting. I don't know if I should be worried, or just leave it be. AF this past cycle came early, was the same length as it normally is. The only change this month is that I'm not taking my daily B12 pills.

If you are someone who has had this in the past, were you able to get KU during that cycle?

Sorry, loaded questions.
