I am a few days late on my period and have taken multiple at home tests and had a blood test from my doctor: all negative. Then yesterday I decided to take another at home test and there was a faint line. This morning, I took 3 different tests with the same urine. Two were definitely negative and the other had yet another faint line. Am I imagining the faint line? Is it possible to have this many negative tests and still be pregnant?
