Can the pregnancy test fail?

yes atest can lie.It can be that you is and it will say no or it can say yes and you not.

There is always the margin of a home pregnancy test failing, be it from an error on our own part, an expired test, et cetera. If you test too early, it won't be able to detect very low levels of HCG (pregnancy hormone it looks for). Make sure to follow the instructions, it's good to test in the morning with a fuller bladder after you've missed your period (as difficult as it can be to wait).


Re-testing is always a good idea if you're unsure!
