Egg white CM after ovulation?

I had 2 days of positive OPKs earlier this week and BDd on both days and on the day glow predicted was my ovulation. I also temp and my temps jumped way up after the ovulation day which should mean I ovulated. But this today I have some egg white CM--not as much as before ovulation--but a decent amount. Also my OPK was negative today too. So is it possible to have egg white CM after ovulation?
