CM - creamy, only after checking internally... same as yesterday
CP - a bit higher again, which is a good sign
BBT - Why oh why does my basal body temperature keep dropping? This is completely bizarre... or, as M. Night Shyamalan would say, "What a twist!" (If you have no idea what that's a reference to, check out this video)
Sleep observations: I woke up early again this morning, though only a half hour earlier than usual. I'm not sure what that means, if anything, especially since I take my temp and then proceed to fall back asleep for another few hours anyways.
For my own curiosity's sake, I checked back in my previous charts to try to find other charts which showed similar pre-ovulation patterns of a sharp, steady drop in temperatures like I'm experiencing this month (currently a drop of 0.7 degrees in 8 days) To my surprise, I found a few that looked somewhat similar.
Cycle 2 - Though a sharper drop than my current one, in this cycle I dropped 0.9 degrees over 7 days, and ovulated a week later.
Cycle 20 - Again, this had another sharp drop in it. In total, it was a drop of 0.7 degrees in only six days, with ovulation five days later.

Cycle 30 - This one had three drops of 0.2 degrees or more... a total drop of 0.9 degrees in six days, with ovulation only two days later.

In each of these, I had a short period of slightly-higher-than-the-dip temps before ovulation actually occurred, and in two of those three months, my cervical mucus pattern did not match up with ovulation. So, it looks like I may have a while to go yet before ovulation, but at least I know... and we all know that knowing is half the battle.
