Yes, it is possible. There may not be enough HCG (pregnancy hormone) in your urine to trigger a positive result.To see if you really are pregnant, take another test :)
There is a small chance that a pregnancy test can result in a false negative. If you feel there is some doubt, take another test. It might also be a good idea to consider seeing a doctor.
A negative test could also be the result of a phantom pregnancy. A phantom pregnancy is where you basically fool your mind and body into thinking it is pregnant. You will still experience pregnancy...
I'm experiencing the same thing. I don't know if the sick stomach, lower back ache, and tiredness are because I am still nursing my first and my hormones are wack, but I've failed the pregnancy test....
