Is this a bad test/do you see a line??

Hi! This is my second time testing in 4 days, the first time I swear there was a faint line and the lady who tweaked it seen it too (I'll post that as well). Well I tested again this morning because I'm getting heartburn with everything I eat, and my sense of smell has heightened to the point I feel like I'm a dog, but no line at all. Ugh. But then I got looking at the first line that did appear, it looks faded a bit to me? Did I get a bad test? Someone help I'm losing my mind!

The first picture is the lady's tweaked from a few days ago, the second and third are todays.. thank you
