In your experience, how common are false negatives when the test says it should work already?

My period is on time with this app’s prediction 95% of every month— ON the predicted day.

3-4% it is late 1 or 2 days.

Now, 1% or less it is late 3+ days.

My period is currently 4 days late. I can count on one hand how many times it’s been this late.

However, I’ve taken 3 pregnancy tests in the last 2 days (2 were First Response, 1 was a digital one), and all said I am not pregnant.

Those tests are supposed to be accurate FIVE days before my missed period and it’s currently 9 days after that. I can pretty much trust I’m not pregnant, right?
