Hi Ujil
There are a few things you can do - which may help you.
1. Within the history panel - take snapshots (click on the camera). . You can combine this with number 3 automatically by turning on Automatically create New Snapshot when saving in History options. These snapshots are there even if you go beyond the number of history states but will remain only whilst you have the document open
2. A practice I always recommend - Save the document regularly at key-points using Save As and incremental filenames i.e. filename001, filename002 etc. These incremental versions, as well as giving you history points, can be a lifesaver if you have a crash or realise you need to start again from an earlier point.
3. A variation on the above - Save the document regularly using Ctrl+S to your Creative Cloud Files Folder and ensure that Sync is turned on. When you overwrite it, Cloud storage moves the previously saved version(s) to the archive.
How useful this is to you depends on the number of documents, the size and the Cloud storage in your plan.
4. As others have said, the history log gives you a text list of adjustments
