As you navigate your fertility journey, you’ll quickly realize, there is an entirely new language made up almost entirely of acronyms.  It was incredibly frustrating and overwhelming. It made me feel like an outsider in a club, that I didn’t even want to be a member of in the first place. That's why I created this comprehensive list, to make it a little easier to crack the code.
