If it is negative, you can rely on it, but there is always a risk that it is a "false" negative. In this case, to be sure, if you do not have your period in 3 to 4 days, you can redo the test with the first morning urine which is more concentrated. What happens is that at the very beginning, the concentration of pregnancy hormone is not high enough in the urine for the pregnancy test to hate it.
