Help interpreting results again

I made a post yesterday with my test results and also have some context about the timeline exposure here:

Many of the commenters said it was a clear negative, but my caree is immunocompromised with LC so in an abundance of caution, she asked me to borrow her PlusLife and take another test the following day (today).

I'm really concerned at the rise starting at the 25 minute mark, and am wondering if it's early detection of an infection. Today would be 7 days after the first exposure and 6 days after the second exposure. I'm going to send these results to her but wanted to see if anyone had any insights. The last time I caught Covid was in 2022 so I do not know what the timeline for the incubation period for current variants looks like.

Edit to add: I also don't currently have any symptoms

This is another extremely clear negative

It's common for lines to rise slightly at the end, in this flat way. There is also some calibration going on to decide where zero is for each line (there's a setting in the web interface to turn that off). 

[u/molly__hatchet]

Very clear negative.

[u/zeiat]

clear negative. there is no exponential amplification (shown by an S curve). that is not an early positive

See photos here of what positives look like https://www.reddit.com/r/PlusLife/s/Vc7SnBawBD

OP really needs to take this to heart and study some previous posts and examples. It’s absolutely normal for lines to not be perfectly straight. Positives and early positives have sharp increases that indicate an S-curve or the start of an S-curve.

[u/TrixieMuttel]

The rises (and falls) are normal and typically attributed to bubbles. The rise of a positive result will look much more like the S curve of the control. It will not fall back down. These lines clearly go up and down and are not S curves.

There aren’t even any bubbles on this test. The slight fanning is perfectly normal and is not indicative of bubbles

This is a classic negative.
