Pink spotting 2 days?

Hi everyone,

So I had my period nov 18-21 as usual and not due for AF til Dec 21. Have had unprotected BD.

But for 2 days (the 11th & 12th) I had very faint pinkish brown when I wiped sometimes but very seldom and it is gone today on the 3rd day.

Just wondering if anyone has any insight on why I saw the pinkish brown? It was honestly not a lot at all. But I thought AF was just super early. 🫤
