Confused as to what is happening

I got a vvvvvfl a couple days ago then started bleeding yesterday after getting a vvv faint positive yesterday and this morning it looks darker than yesterday. So what is going on? I had a chemical last month but the line didn't get darker. The first picture is from this morning.

UPDATE: I took another test because people weren't able to see the line on the other two tests. I took the picture 1 minute after I took the test. Saw a line right away. It looks blue in person just hard to get it to look like it in the pic.
