Meredith - I am assuming it will be the 23rd as that will be 19 days past IUI but If I get to Monday without AF, I'll call the Nurses and ask.
I am tempted to do the HPT, however I took ovidrel last Thursday and from what I have read, it will give false positive for atleast 10 days so the earliest I can test is Sunday.
Keeping my fingers crossed for us that the 23rd will be a great day for all 3 or us!
