Or even heard of it?
Part of me really wants to try next cycle:
http://www.amazon.com/Fairhaven-Fertile-Focus-Ovulation-Microscope/dp/B000S2O1CI/
It is only around $30, which seems so cheap in the TTC scheme of things.
Some people swear by it. Some people don't fern.
But I think it is really interesting.
I'm just getting fascinated (and mildly frustrated) by all things TTC.
