Negative urine

Hey ladies! So I just went to the doctor for the second time to get a Urine test done. Once again it came back negative. I’ve take 4 pregnancy test at home and they have all been positive. I took one last night just to double check. When I got back from the doctor I took another and it was positive. I would be 4 weeks and 4 days. I finally demanded a blood test and now I’m patiently waiting for that result.. has this happen to anyone else?? I have positive test here! I’m trying to stay positive 😭
