Deep breath.....breath in.....breath out

.
I've only just begun trying to monitor myself in the various ways I've read. The problem is that I've started in the
middle of my cycle and that is making me crazy. I wish I would have started at least a few days earlier because I think I started
after O. I want to TTC in September and I'm doing AI from a Sperm Bank. I've got my cycle on a program call Hormonal Forecaster going back to March, but I wasn't temping or checking CM because, frankly, I didn't know I was going to hear that very loud
TICK TOCK and was going to decide to TTC

. I'm 41 so I don't want to wait and chart for a couple of months (again: tick tock). The Hormonal Forecaster predicts that I'll O on the 5th, 6th, or 7th and shows a "Pregnancy Advisory" between the 1st and the 9th. The sperm bank would like to have the shipping date a week-two weeks before it's to be shipped. Should I wait to get AF and then order it to get here on the 1st (if AF comes when it's supposed to)? I plan to do OPK from the first on and need to have the

here when I see the LH surge (it will remain frozen for at least a week).
I will be shipped 2 samples. Should I do one on the day I get a LH surge? What do you suggest for the 2nd one?
