Has anyone ever had a negative Drs urine test and still been pregnant?

Had one positive hpt and about 50 negatives!!! Went to the dr for urine test and it was negative.. She gave me the reference for blood test and transvaginal ultrasound but I am so confused!!! I know it was positive, could the office test be wrong? It was almost the same test as the one I took, dollar store
