Any one lines continue to look like this?

I took these tests over the course of 4-5 days now I believe . hence the reason they look dry but the last one you see I just now took another faint . has anyone tests looked like this and was indeed pregnant? I wonder why they continue to stay light . also when I took this one it was like the dye sat on the test like half way all the way pink I picked it up and when I looked close the dye started to run past the control line . I hope im explaining this right . I was like omg . but has anyone experienced this ?
