Sorry in advance for the TMI...

I'm currently in the TWW - 10DPO today. The past couple cycles (all post-BC), I've noticed some spotting the day or two before AF, which gradually turns into AF. This cycle I've had the same but different. Noticed a single brown spot on 7DPO but nothing when I wiped or later that day. Yesterday (9DPO) I think I saw some brown too but was wearing black underwear so not totally sure. Extremely light tint noticed when wiping. Today brown spotting/discharge again and I wore a panty liner. Noticed it in the morning, nothing during the day and again at night.

Anyone ever experience this? Usually AF comes 12-13 DPO so this spotting is earlier, if that's what it is. It's also been a different color and frequency than before.
