Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
Please review the link below and try the recovery 'places' to look before we check your settings to fix your issue.
This should be done from a computer, not a device if possible. And in a browser as well as your email client on your computer.
Even if they were deleted, gmail holds for 30 days by default for deletions. We should be able to pull them back

Please update when you are done following the document to go from there.
