When I’m first adding an object to the scene I can select the number of vertices it will have but after I added the option is gone. Is there a way I can select the object and edit this or do I have to delete it and make a new one. I know I can ctrl+r to add an edge but this isn’t logical. Thanks in advance for any help.

No, you only have the options at the time you add the object
You can go back in history:
