Yes. It is quite possible for you to be pregnant because you might have done the test in very yearly pregnancy. At this stage, hCG might not be high enough in the urine to give a positive result.
If you still suspect pregnancy repeat the test a week later because by that time the hCG production increases.
Similarly, if you perform the test after drinking lots of liquids, the dilute urine can give a negative pregnancy test even if you are pregnant.
