Question about pregnancy test

I don’t have pictures of the test I took but I wanted to see if anyone has experienced what happened to me. So I peed on a first response test and I set it down to load. While the pee is running across the screen the test line (1st line) shows up and it’s clearly positive. My heart was beating fast and as the pee keeps going across the screen the control line (2nd line) shows up! But then the first line disappears! The test was negative. I never seen that happen with a first response. Can anyone relate?

****I can Move this somewhere else if need to but I figure since a lot of us have taken test here this would probably get the most response.
