HPT positive, drs office test negative

Hi everyone.. I had an emotional day today. I just hit a little over 4 weeks and got in with my doctor to confirm the pregnancy. I did a urine test at my doctors office and it came back negative but I took 3 tests this morning and yesterday that have come back as a faint positive. 1 early response test, 1 digital and 1 regular strip test. The doctor said I was not pregnant… has anyone else ever been in this situation? I don’t really know how to feel.. am I pregnant or not? 😞
