The Infertility Language

As you enter to the world of fertility issues and infertility struggles, it feels very overwhelming. No denying that. You are struggling with so many different emotions related to your body, your role as a person, your goals related to your family, the struggles that may be placed on your relationship, and so much more.

But something that seems pretty unexpected is that you are also learning a new language. The various Facebook groups and support related to fertility and tracking apps that you may be using have a language all of their own. A common sentence you may read is “My DH and I are TTC now, we are in the TWW and just want a BFP”. And everyday dictionaries don’t have a key for fertility treatments. (Although, they totally should). But luckily, we got you.
