Can my dr be wrong?

So about a little over a week ago I took the first test. Then went and did a urine test at the dr. While waiting for those results went and did the digital. Last Monday was told my urine test was negative. Waited til Friday to test again with a 25 mui test. Both lines came up in less than a minute. Last test was this morning not fmu same thing. Oh and the other 25 mui test was afternoon urine just like at the dr. I asked my dr to order blood work on fri and he still hasn't done it. I know it's still early today. I have a history of getting false positives but normally I would have started by now. My dr basically thinks I am crazy.
