Unclear if ever were: Urine pregnancy tests are very sensitive, but serum (blood) bHCG tests are even more sensitive, and are not prone to human error interpreting results like home urine pregnancy tests are. If your urine pregnancy tests were positive, but serum bHCGs test was negative on same day, then you were probably never pregnant. It really depends on timeline you did these tests.
