Faint line negative at doctors

Laci

If I’m early enough along can the urine test at the doctors come up negative and I still be pregnant? I had two test both showed very very faint blue lines so the next day (Tuesday) I ran to the doctors to take a urine sample and the results came back later that night negative. My husband and I let our guard down and actually got excited thinking this was it and now I am so upset. Has this happened to anyone?
