What is this line?

Sa

The first test was taken this morning and I see a faint positive line, but there’s also this blue line. What is the blue line? It’s not present on any of the other tests.

The second pic is of a test I took later in the day today for comparison. No blue line and no faint test line.

Both pictures were taken within 1 minute of taking the tests.
