How accurate are these?

3 days before period is due. This test was taken within the time frame. I’ve taken two of these today - one this morning around 11:30ish and the other around 5:30. Both times showed a faint second line. The photos shown are from the 5:30 testing and I held my urine for over 3hrs (took a nap and didn’t use the restroom) not sure if the photos would pick up what I think I see or not. 🥴
