Can a pregnancy test be negative one day and positive the next?

Can a pregnancy test change overnight? The answer is yes. Not only can you get a negative pregnancy test result followed by a positive, but you can also get a positive test result and then a negative.

Why do blue dye tests give false positives?

The short answer is anything but a blue dye. That’s because blue dye tests are notorious for evaporation lines. These evaporation lines tend to have a grey tint to them thanks to the blue dye running across during the testing process, making them look like a faint positive when in fact no hCG was picked up.

How do you tell if it’s a faint positive or evaporation line?

Positive Result: If positive for pregnancy, there will be one horizontal line intersected with one vertical line, forming a plus sign. The evaporation line typically shows up as a very faint, thin and almost colorless vertical line. If you test early and have low levels of hCG, the vertical line may be faint.
