Bad news?? I'm confused? Miscarriage?

Hello! So I got 2 positive pregnancy tests on October 8th. I went to the dr. Today and they said the urine test they conducted came back negative. They done blood work and should have results for me in the morning. Has anyone else had this happen? We're you pregnant when the results came back? Or did they inform you that you had a miscarriage? I'm so nervous & scared. But I'm hoping that it's because I took the test later in the day. They didn't get to see us until 1:00 he had to deliver a baby and I had already used the bathroom several times. And the best time to test is first thing in the mornings when the hormones have built up in your system over night. So fingers crossed for me!!!
