AF 9 days late

Sooo like it says above, AF is 9 days late today. I took a test the day it was due (Jan 6th) and was negative. Haven’t thought much about it since, because of life being busy. I realized last night how late I was when I went to the bathroom and wiped and there was some brown discharge but nothing else. Today same thing. No cramps, no usual signs of AF just this brown when I wipe. Been TTC since November.

Any insight or similar stories? What ended up happening? You think AF is around the corner, orrrr is it possible I’m pregnant 😍 who knows. Whatcha guys think? Probably gonna test in the morning if no AF still.
