Positive and negative tests

Skye
I got a positive test on the 14th of November I was suppose to start my period on the 12th. I made an appointment at the doctors and went yesterday and did a urine test thru said it came up to light so they said it was negative so then I did a blood test and they ruled that as a negative. So I took 2 digital tests this morning one was positive one was negative. I'm literally so confused and the doctors office recommended nothing.
