unless anyone was having scans it would be impossible to know for sure. I'd have thought that temps wouldn't rise much until both eggs were out in that case because the oestrogen being produced from egg #2 would keep cooling the temp after #1 was released
I've seen it written many times that some eggs can survive 24-48hrs after ovulation. I guess this all comes down to egg quality.

sorry, I missed that question. You ALWAYS get at least 2 peak days when using the CBFM - the day of the LH surge (i.e. day of the pos OPK) and the following day is an automatic one because you usually OV on that day.
If you have a long surge you might get an extra peak day.

Thanks Rainbow, ok so let me get this straight, the FIRST PEAK is the day I would ovulate?

no, usually you'll ovulate on the 2nd peak although it IS possible to OV on the first peak, but the first peak is a very good day for BDing if you want to conceive either way

I always O on the day of the temp dip. When your temp rises, it means O has already happened (temp rises due to progesterone rise after O) FF goes by temps, so if you have three days of high temps above the previous 6 days, that is part of the way it determines O. It was guessing CD 21 but after a few days of high temps realized you O'ed on the 20th. temps only tell you when O has passed, not when you will O in the future.

But the corpus luteum begins to release progesterone and so the first egg's CL would begin to produce progesterone on its own timetable and that would be represented in the temps.
My understanding based on numerous sources is that eggs cannot survive for 48 hours. 24 hours is the absolute max and most eggs expire sooner. The 48 hour time period for potentially being fertile, is based on the idea that a person releases one egg and it lives to its maximum lifespan and then the person just happens to release another egg that then also lives to the maximum but that is only meant to err on the side of safety in those using NFP as birth control - the possibility of that scenario actually happening is as unlikely as getting struck by lightning. Most of the time when two eggs are released they are released much sooner than that.
There is also the possibility that one of the high temps is an outlier as well which is why TCOYF and the other NFP sites want you to wait for 3 high temps when using NFP as a birth control method. That way, if your first high temp or even two is/are just a mistake, the three day pattern ensures that your egg is for sure dead and gone and you can resume unprotected intercourse. Not because you may be ovulating during those days you're having high temps!! They are trying to ensure that NPF is as reliable and mistake-proof as possible and so the three day rule exists to make sure there is an actual pattern of high temps in place and not one "oops I got too hot when I was sleeping" followed up by a low temp the next day, KWIM??!!!
