Took 2 more tests, please help!

The first test I took at noon today.

Then tonight at 9pm here I took the middle and the bottom one. Why are the lines so faint now? Or are the lines not there..? Please tell me what I’m seeing 😭😭

The bottom one is the same test as the top one, I wanted to see if the result would be the same.

The middle one is a different box.

I am still spotting brown, like a light period now but it does not look red at all.

Edit: i tested this evening and the line is gone..not even faint. I do have an appointment on Monday for confirmation..thinking about cancelling…
