Yeah, I don't have an answer. It looks like you've O'd... but, if you've read my recent posts, you'll know that I'm just as confused as you are

Yours at least got lighter. Mine just keeps getting darker! I think, from what I've read, that your LH surge has diminished. That means you've recently O'd or you are about to O. Your temps should spike shortly. A dip prior to O doesn't mean anything. It's the prolonged rise that marks the fact that O has happened. I think it's at least a +.2 increase in temp over the a 3 day period. That's what I read. No actual experience. We will learn, right?!?!?!?
On a lighter side of things...we're on the same cycle! Although Dh and I aren't TTC this month, I wish you luck and BFP dust!

I can't wait to see your BFP! I hope it happens really soon!!! I think you have this cycle well covered!
