Suggest doing the charting lessons that get sent to your inbox with FF, they have stacks of info to help on these questions and would probably get you up to speed (worked for me :-)
I think the CM (which is different for all women) usually dries off, but some women get egg white even after O, so its possible that anything can occur. You could check the chart gallery to see what other women have reported. I find that pretty interesting.
BTW I can't seem to see your chart, you might want to post the link again.
