Alright wtf? Read the whole thing please

Okay so Friday I had an extremely faint line and went to the doctors office to have it tested there urine test came back negative and the blood test came back negative but my FRER are all reading positive and are having the second line get darker? Anyone want to help me out and tell me what’s going on?

First test (taken Friday mid-day)

Second test (12/30/2018 morning second pee)

Last one (12/30/2018 night)

The last two are one in the morning and one in the afternoon... what tf am I missing here I mean I need a nurse or dr or someone with experience to help me out because I’m at a loss right now
