Faint lines or faulty tests??

These are my sister in laws. (Were both TTC and share everything) they were taken like 30 minutes apart. The first one I thought she didn’t dip long enough and told her to retest. The second she dipped longer. We see 2 faint lines on both but?? Idk. Has anyone used these? Do the lines w this brand just not get dark? Would you consider these positive? TIA!!

Update: not with a urine hold but she took a first response. We both have line eyes but feeling like I can see a vvvvvvvvvvvfl. Thoughts?
