Sooooo I had my follicle tracking today for our IUI tomorrow - I'm a total newb at this. My 'score' was great in some areas and pathetic in others. My lining was 10mm, which sounds lovely and plush. She mentioned that I had the layered effect that shows my estrogen levels were/are healthy. My right ovary had 3 'good sized' follicles - 15, 19, and 22. My left ovary didn't get the memo and pushed out a measly 9mm weakling. Not cool, lefty. So I got my hcg trigger and have had a nice increase in bloating and cramping, so it damn well better be working.
My (stupid) questions are as follows. Please forgive my ignorance.
1. What I've read says the HCG will trigger ovulation in 24-36 hours. I got my shot shortly after 9am today and our IUI is booked for 12pm tomorrow. I'm a little worried that I will ovulate in 24 hours and it will be 'over' by noon. Am I being paranoid?
2. I've also read that the first IUI has the highest success rate. Is that just google-junk or is it true? I'm telling myself it's true either way, since I could use all the positive thinking I can get!
IUI veterans, I appreciate your advice and support!

1. Youl'll be fine. Ovulation typically occurs 36 hours after the trigger and the egg typically survives for 12ish hours.
2. From the studies I have seen your best odds are best for the first 3 IUIs, never heard that odds are best for the first IUI.
