Thanks nothing2lose but just to clarify - so you assume that if my LP has been around 12 days each month that it will be that again this month even though I only ovulated on CD17 and that if I were to get AF on CD24/CD26 that I wouldn't have a 7/8 day LP??
The way I understand it is you will either have a longer cycle (29 days or so) or you didn't ovulate when you thought you did.
