FertilitySmarts Explains Big Fat Negative (BFN)

Big fat negative is a term that has become popular in infertility and trying to conceive (TTC) discussion boards and blogs.

The disappointment of a negative result on a pregnancy test—especially when there has been a significant effort in trying to conceive—can be difficult news to accept and even more difficult to share.

Referencing a BFN can feel like a more detached, and therefore less disappointing, way to communicate to "I am not pregnant."
