Seriously, I have no idea what the infertility/fertility abbreviations mean. I know “TTC”, and that was pretty much the extent. And even then, “TTC” is what we call our transit system here in Toronto.
If you’re like me and you have no friggen clue what people are trying to say with “BFN”, “2WW”, or “DH”, you might want to check out THIS list. In fact, you might want to bookmark it, keep it open, or even print it.
