When you take a trigger shot to bring on Ovulation at a specific time, it injects pregnancy hormone into your blood. Therefore, if you take a pregnancy test following the trigger shot, you will get a positive even if you are not pregnant. They say that the trigger shot can stay in your system for up to 10 days after injections. So, some women who like to test early (before the TWW is fully over), will test out the trigger so that they will know when the trigger shot has completely left their system, and then any positive they get after that is the real deal. That means taking a pregnancy test every day after you take the shot to see the line get lighter and eventually vanish. That means that the trigger is gone. Then any subsequent positive tests mean that you really are pregnant.
Sorry if that was a really long winded answer, but that is the best way I can describe it.
I personally have not done it. This was my first time with the trigger shot, and we thought about doing it, but something about testing every day and seeing a positive test when I wasn't really pregnant just didn't seem like a good choice. So I am going to wait until 14dpiui (which is 2 days after I expect AF, actually), and if AF doesn't come, then I will test.

Ya, that sounds like a lot of testing and expense. And kinda hard to see a positive line disappear into a negative.
Oy, the 2ww... bleh.
