There was a lot of confusion as to at what point the test can be used, especially regarding early testing (before the missed period). We created a visual timeline to clarify this:
- Change of 13-16 days to two weeks, less complicated to work out (checked online and two weeks is the standard time).
- Two separate diagrams as trying to do it one timeline is confusing – seeing as the times could overlap. There are two milestones, the time of fertilisation and the time of the missed period that have to be considered separately.
