Looking at your chart I'd say you O'd on CD21 as you had wet CM until then. You shouldn't get it after O.

Also temps after an early m/c are usually erratic and I notice you had one last cycle so you can't really go by the temps in the first half of this cycle, your CM would be a better indication and cos that didn't change til CD22 & you got a rise in temp then too it's likely that you actually O'd CD21. Hope that helps.

I also noticed that your temps were quite low last cycle for a pregnancy cycle - FYI I've read somewhere that low temps like that are a sign of low progesterone and that m/c will often follow.

Anyway if you know your usual LP wait til you reach that after counting from CD21 and test again then. Good luck.
