Try looking in the "Recently deleted" folder:

Eg: says:

"Recover deleted photos or videos

When you delete photos or videos from the Photos app, they’re automatically saved in the Recently Deleted album for 30 days. If you accidentally delete a photo or video, you can recover it and restore it to your Photos library.

To recover deleted items, open the Photos app tap Recently Deleted (below Utilities),

then tap View Album. Unlock the album using your iPhone passcode, Face ID, or Touch ID.

Tap a photo or video,

tap Recover,

then tap Recover Photo or Recover Video."
