TTC: What all those trying-to-conceive acronyms mean

If you find your head spinning trying to understand those fertility message boards, here's a breakdown of all the terms and acronyms you'll need to know.

When I first began struggling with my own issues four years ago, I found myself scouring online message boards and reading other people’s personal accounts of their own fertility journeys. The problem was, I couldn’t understand half of them because the accounts were peppered with acronyms like BFN (big fat negative) and TWW (two-week wait).
