Anyone use these?

Anyone use the first response comfort and check tests? Has 3 regular first response and 5 just strips. I swear I was seeing a vvvvfl, so I kept the tests so I could compare the next one I took. When took the next one I seen the same thing, so I pulled out the other test to compare the lines and the other one the line is more noticeable now. I’ve taken 3 of the strips and all 3 I thought I seen a vvvvfl on and later the line was more noticeable and is pink. Anyone use these and have this happen? I’ve never had this with a first response. Thanks to anyone who answers

Edit- - I only have a picture of the tests after they had the lines more noticeable.

I feel like it’s not as noticeable in the picture as in in person.
