Spotting help!!

Af was due on the 3rd. Day of expected af, all that showed was a very light amount of brown discharge, so I put in a tampon and when it came time to change the tampon, nothing was on it. Normally before I start af I get brown discharge and before the day ends, it’s full on period. Now it’s the 6th and had a little brown discharge yesterday again one time, but again, no red blood. I cramp on and off. This morning, there was nothing again discharge wise when I checked but the normal vaginal discharge, no period.

I know the only way to know if I’m pregnant is to test, but I’m so sick of bfn that I’ve been avoiding it. Anyone else have this and af still show or were you pregnant?
