4th day of flashing smiley but having EWCM

Has this happened to anyone else? I'm on my 4th day of having flashing smileys on my CB advanced OPKs but just this evening I've noticed my CM has changed to a clear egg white consistency. I know that's your most fertile CM. I would have thought I would be getting my surge soon but nope, still flashing smiley. Praying I get my surge tomorrow!
