5 x home tests but dr says negative!? Am I pregnant??

Elise

I had my last period nov30, spotted dec 25 then post spotting got 3 positives, went to the drs to confirm pregnancy, his test was negative on dec 31, I came straight home and took below tests!? 5 positives and dr negative! Waiting on blood results. Could this be chemical pregnancy? I have lots of symptoms of pregnancy. Has anyone else experienced this???
