Egg white CM and negative OPKs

So I had 3 high days and 1 peak day of OPKs and it's now the 6th day and I've had a negative OPK.

I've had egg white cm all throughout and now it's 6th day and I still have egg white cm and sore boobs. Ovulated either yesterday or the day before.

Does egg white cm usually carry on after ovulation?
