CM question!

Hello ladies, 
​I just finished my period on the 11, I also did the BD on the 11. Since then I'm now getting whitey watery CM, obviously I know the the chances of getting pregnant on that date is very unlikely. But I just don't understand this CM!
​I have never had this much of white watery CM before... Anyone knows what it means ?
