Pregnancy test help

Jess • Been with the love of my love for almost 8 years, married 17/08/19 baby boy 💙 👶 05/10/2019 baby boy 💙👶 April 2022 baby girl 🩷🧒 March 2024

I had a period last week or what I though was a period not sure now, took a pregnancy test got a faint line, took a digital at the beginning of the week positive 1-2, took another one this morning came back negative but still faint line on the first response

Has anyone experienced anything like this before?
