Strange test results!

Hi guys, im 11 DPO and 5 days from AF. I took the test shown in the first photo Tuesday evening and as you can see there is no sign at all of a second line. The second photo is a test I took this morning, it doesnt have a vivid line I know but it has a clear indendation of where the line would be, which the earlier test didnt, and I swear I can see it on the photo? Anyone had a similar experience? Tia x
