I can see it.  And you're right, your pre-O temps are quite high. I'm sure this is lingering progesterone from your previous pregnancy. I'm so sorry for your loss! How far along were you? If you were a bit farther along then the hormones can linger for some time.Â
Â
If I had to guess, though, I'd say that you did O and probably on CD 17. Since you don't have CD 18's temp it's difficult to say, but based on your CF and CP, CD 17 seems the most likely. Your coverline would likely be around 97.4 or 97.5. You seem to have the "calm before the O" as I like to call it where your erratic/high temps dropped and leveled off for a few days and then spiked. So for now I would say you are 10 DPO and could test tomorrow if you wanted or wait a couple days to see if AF shows.Â
Â
There is a slim chance, however, that you only just O'd around CD 26 where your temp spiked high, higher than all your previous temps. Your CF and CP do not support this assessment, but things can be quite off when regulating from a hormonal event like a miscarriage. So in the event that you get BFN's and no AF for another week, this may be the cause.

Good luck and keep us posted!
