A negative pregnancy test at 12 weeks could occur due to a rare phenomenon known as the 'hook effect'. This happens when high levels of hCG (human chorionic gonadotropin) interfere with the test's ability to function correctly, leading to a false negative. Diluting your urine and retaking the test, or consulting with a healthcare professional for a blood test, can offer clarity. Remember, it's essential to seek medical advice if your pregnancy test results don't match your symptoms or expectations.
