It is possible to receive a false negative result on a pregnancy test, especially if it was taken too early. If you are experiencing symptoms of pregnancy such as frequent urination, backache, and thick white discharge, it is recommended to wait at least one week after your missed period before taking another test. This will allow enough time for the hormone levels in your body to increase and be detected by the test. If you still receive a negative result but continue to experience symptoms, it is advisable to consult with your healthcare provider for further evaluation and possibly a blood test for confirmation.
