Where is my AF?

So dec 30 I had a very little amount of spotting red blood that lasted maybe 2 hours then went away, along with this I had cramps for 3 days before. On Jan 1 the day before my expected AF I started having brown discharge which is normal for me, normally after 2 days that goes away and I have my regular AF. Not this time though I’m on day 5 of very light brown spotting. It seems to even be getting lighter like it’s going to go away anytime. Has this ever happened to anyone? Is it normal?
