I will have to read it again because you wouldn't know you O'd until after the thermal shift kwim?

I got that stuff about being anov from the section on charting after birth and while breastfeeding. I think the scenario was if you had not had an ovulatory cycle after giving birth but were getting intermittent patches of fertile CF. Personally, I would go with what you've said. If I have fertile CF and then dry up but don't have a thermal shift, I consider myself safe after the 4th dry day. That's because I know I have long cycles with at least 2 patches of fertile CF before I O. I don't know how that applies to others who don't have that pattern. For example, if you are ovulatory and your cycles are relatively normal length and regular and you are having an out of ordinary cycle where you get fertile CF and then dry up but don't get a thermal shift, you could still O at any time and, therefore, still be fertile.
The peak day rule says you are safe the evening of the 4th consecutive day after your peak day. The temperature shift rule says you are safe the evening of the 3rd consecutive day your temp is above the CL. These two should normally coincide so the 4th day after your peak will be the 3rd day of high temps. However, if they don't match up, you should wait until both rules have been met before considering yourself safe.
There's the patch rule that says you are safe the 4th consecutive nonwet day after your peak day but that's in Appendix B under special circumstances like being annovulatory or breastfeeding. I didn't think that applied to normal situations. Am I misunderstanding or missing another section about this?
