Dang! You're right Jen. I just assumed it would be the first chart that popped up. What can I say, I'm a

!
Anyhow, let me take another look.....
Taking into account that you don't always HAVE to have a dip, just higher temps for three days...it could be argued that you O'd around 13 or 14 and if you gave yourself a 12-13 day LH it would make sense that you spotted when you did. Your temp also took a dip right before you started spotting (day 26). Was it you who posted that the nurse told you to count spotting as a period, or was it someone else? If that were true, and the spotting was counted as AF, you may have started a new cycle around CD29 (which would coincide with another 13-14 day pre-O phase with a shot of EWCM on the day you have listed as cd 42. Hard to say because there is missing info for cd44-46. It might mean another 4-6 days before any spotting again.
Talk any of my advice or observations with a big ol' grain of salt. That part of my earlier post is still applicable.
Don't know if I helped or was just confusing!
Take care.
