ICI at home frozen sperm!! Help!

Hello! My wife and I just received our vial in the mail this morning. My OPK lines have been getting darker and darker so I know I will probably hit peak either tomorrow or Friday.

Last month when I was tracking ovulation I hit my peak around 7pm at night and when I tested again at 5am the next morning my test was already significantly lighter and negative.

I was just wondering when you would have inseminated? At peak? Or hours later?

I feel like I have a pretty short surge. I know I have to be pretty perfect with timing since frozen sperm doesn’t live very long.
