Negative FRER and VVFL on others?!?

Cl

I am 9DPO (I know I’m testing early).This morning I took a FRER and got a very faint line (bottom of the second photo). I took another FRER at 2:30 PM and it is negative, so I went and dipped a couple different tests (first photo) in the same sample and those came out with faint lines. HELP! What does this mean? Why would a FRER be negative but other tests show positives? The photos were all taken in the time frame.
