Feeling Down after canceled IUI

So far I have had one IUI with donor sperm. My follicle was a great size and lining was good as well. The first IUI was a BFN.

Moving into my second IUI I peaked over the weekend (my clinic isn't open on the weekends) when I went in on Monday it was clear we had missed the window for IUI. I have been down since then, I'm trying to find hope within myself that this will all work out.

My doctor plans to trigger only if I haven't ovulated on CD13 (generally ovulate before then). Any insight or encouragement would be invaluable! Thanks!
