AF due.. Fertile CM?

Joanna
Hey all, 
I had egg white CM during my time of ovulation, and my period is due on the 6th. 
I've got a little nipple tenderness, but nowhere near as bad as my usual pre-menstrual breast heaviness. Also my CM is egg white again today.. 
Anyone else had this? Could it be a BFP month? I don't want to test until AF is late..
