Morning!
Chrissy - looks like your temp has come down at the end of AF, which is quite common. Lots of women have high temps at the beginning of the cycle, which then drop as AF finishes. The thing about a cold is that unlike a fever, it isn't necessarily accompanied by high temps. Also, if you have a cold, you're more likely to be sleeping with your mouth open - which will give you a lower reading. Best not to worry too much about it, but to make sure you note 'cold' in the FF notes - add it as a custom sign if you want to make it really clear.
NickyB - welcome! It's definitely a confusing chart. The cold temps in the bedroom will make a difference, but I'm not sure how much. The thing that's really confusing, however, is that you have two temp shifts - there's the one at CD22 as well, and the temps are high for 3 days, so it's not a one-off. But that's when you say the bedroom was cold... The other thing is that there are only 7 temps under the coverline, less than a quarter of the pre-(FF)O temps, which doesn't make sense. How regular are you normally? And what was your range of temps last cycle?
I'm going to stick my neck out here - I'm not convinced by the 29dpo ov, though I wouldn't rule it out. I think it's more likely that you ov'ed on eitherCD22, or CD27. If CD22, I think you should be expecting AF in the next couple of days. Looks to me like you may have had a dip at 4/5 dpo (quite usual - not an implantation dip) - there are several charts showing a dip below the coverline at 4/5 dpo, then rising again above it. Personally, I'd draw the coverline a little lower, at 36.1 or 36.05. If CD22, you'd be 14dpo, and looks like your temps are coming down for the end of the cycle
. If CD27, you'd be 8dpo - there'd still be an outside chance, as you bd'ed on CD25. The FF coverline is fairly arbitrary - take out the C CM on CD29, and I bet the coverline would shift downwards a little and the crosshairs would move back a couple of days.
The other possibility is that you still haven't ov'ed, and/or that the cycle is annovulatory. If you discarded the temps that you say were taken when the room was cold, and drew a line from CD19 (can't work out if that was an affected temp or not) to CD28, it wouldn't be obvious at all that you'd ov'ed.
What happens if you take the CM out of the FF chart? Problem is, CM is probably the most difficult fertility sign to chart correctly because you may not always notice it, even if you're looking, and you may not categorise it 'correctly' or even consistently.
Sorry - I know this doesn't help much
I guess you ought to go with the later possibility of CD27, but don't be too surprised if AF arrives in the next couple of days
Of course, I hope for your sake it doesn't come at all, and there's definitely a chance with both dates. I'd definitely second the suggestion of OPKs next cycle though, it's good to have as much help as possible!
