HELP!!!!! Faulty tests?

So confused. I ignored that line on the left as it is not in the "designated" test area....

Top 3: top- 2nd test this morning, middle- fmu this morning, bottom- fmu yesterday.

I thought it was curious as why it looks darker. So I pulled the bottom ones out of the trash.

On my way to buy a digital..

Positive? Faulty tests?
