I will keep that in mind and ask if nothing happens by Friday -- the doctor didn't mention it, but that may well be because he has no reason to think it would be necessary as yet. Our first time around (which succeeded) we did the follie-checking u/s on CD13, and based on the bloodwork that day they scheduled the IUI for the morning on CD15. That morning the monitor showed the surge (so I knew we were getting things right!). Interestingly, the Magic Egg last time was a whopping 29 mm on CD13.
Other cycles, I have O'd later though -- CD17 -- according to the monitor, so I will definitely ask. Thank you very much for the suggestion -- since we were so lucky so quickly before, I don't know all the things to ask about!
