Where did my saved project go?

Hi all, I worked on my project for a good while yesterday, hitting ctrl + s many times throughout the day, and when closing the project I clicked save in the popup box, but when I just opened my project my entire work I did yesterday is completely gone.

I am new to UE5, so I don’t know what is going on. Any help is appreciated. Thank you.

Edit: I figured it out: it was the the level I was trying to find within the project, but it had loaded the first level that was made by default when making the project. Phew.
