Hi Sammy. I've just seen your old thread about the cock-ups at the clinic. I think all bets are off now! It seems they prescribed you the contraceptive pill(!) which you took for two days. Have you had the hormone tests that were delayed by it yet?
The estradiol in the pill is a form of oestrogen/estrogen, and the pill works by suppressing ovulation. I don't know too much about the quantities, but I guess that a) it's highly possible that the addition of hormones has caused ovulation to be delayed this month and b) the CBEFM will have picked up on the higher-than-normal level of oestrogen, which is what triggers the High. As I said before, the CBEFM is programmed to give HIghs until it gives Peak, or is overridden by pressing the m button for your period.
Basically, I really don't think you can read anything at all into this month's CBEFM/OPK results - the clinic has screwed everything up for you. This is not to say that you won't/can't have conceived - simply that until you get AF (or a BFP) there is just no way of telling whether or not you have even ovulated, and thus when to expect AF or when to test.
I'm so sorry - this is not what you want to hear. But I would say that if I were in your shoes, I would write off this cycle, and just try to forget about TTC till the next one, because I think otherwise this could cause a great deal of stress. If you don't get AF in the next two weeks, try testing with an HPT again but be prepared for it to be neg - you may not have ovulated yet. I really wouldn't bother with the CBEFM for the rest of this cycle - the oestrogen levels in your blood will have tricked it.
I know this probably doesn't help much, sorry...
