Rarely this can happen. Occasionally you can have lab error, human error or in some cases a pregnancy that was present but has resulted in miscarriage. HCG leaves the blood first and then urine thus allowing for an HPT to show positive neg. What is more likely though is that either you had a false positive test or what is referred to as an evap. Some pregnancy tests will form a "positive" line after the time limit as the test dries. Makes sure you followed the tests directions exactly and only read the results during the correct time limit. If you're still unsure retest using a different brand of test.
