HELP!!

Teressa • mommy to a princess 😙👑❤ 11/17/16 baby boy due November 2022 🥰🫶🏻

So I got what I thought was a clear positive this afternoon. (The bottom strip on the chart) and I took another one just now because, and it’s significantly changed. Did I catch it on time? Or was I wrong about it being positive?!
