Half of a positive line?

A

So I took a test today (9 dpo) with SMU and I got the faintest line. Then I took another test a few hours later and got a very visible second HALF line. Only the top half was obvious. I think the bottom half was super light and barely visible. Has this happened to you? The top photo is from this morning and you can’t even see the line, the bottom is from this afternoon and you can see the top line on the left side.
