Positive and negative?

Has anyone had a positive and negative on the same test with the same FMU? If so what was the outcome?? Like I feel like maybe I can see the faintest line on the second one but it’s sooo weird! And definitely got my hopes up! :( I even tested with clearblue too and I feel like there’s the faintest line there too so now I’m unsure :(! First tests was FRER

Here’s the clearblue!
