Pink discharge, no AF? Help!

Katey
Kinda TMI! 
​I'm due for AF tomorrow, yesterday night I had pinkish discharge, like the kind you get right before you start, so I expected to wake up this morning and AF to be here, or start sometime today. Well the pink is gone, it's just regular dry/damp tackyness texture, no cramping or sign of AF, with 2 bfn
​I've never had this happen before?
