Is my test accurate?

I’m 12 days past trigger, 11 days past <a href="https://glowing.com/glow-fertility-program">IUI</a>. Positive pregnancy test this morning, but vvvery faint.

I have back pain, some cramps, fatigue, moodiness. Going to test again tonight and tomorrow morning to see if it gets darker or becomes negative. Beta #1 is Friday.

Curious is anyone else has had this happen.
