egg white confusion! please help!

Francesca
I am supposed to start my fertile window today, but not actually ovulate until Sunday. This morning I had some egg white discharge. Very gel like not watery at all. Also slight cramping. Am I ovulating early? My last day of my last period was the 19th. 
This is such a confusing process for me. If any ladies have any insight that would be fantastic! Thanks in advance!
