Two week wait
Also written as TWW
The period of roughly two weeks between embryo transfer and the pregnancy blood test.
In plain English
It's the stretch of about two weeks between your transfer and the day you can test, often described as the hardest part of the whole process emotionally.
Why it matters
There's little you can do medically to influence the outcome in this window, so a lot of people find it helps to plan how to get through it emotionally.
