Two Week Wait

The two-week wait (TWW or 2WW) refers to the estimated period of time between a pregnancy attempt and the date where it is most likely that a pregnancy test is able to accurately indicate if the attempt was successful or not.

Pregnancy tests work by detecting hCG levels in urine or blood. It typically takes around 7-12 days after fertilization for hCG to be detected in blood, or 12-14 days after fertilization to be detected in urine.
