It sounds like the page you are trying to edit is semi-protected: "Prevents unregistered and non-autoconfirmed users from uploading new file versions, editing, renaming, and/or creating a page (if it does not exist)."

After 4 days, your account will receive the autoconfirmed status, which will allow you to edit semi-protected pages.

If the page you're trying to edit is fully protected, only admins can edit it. If that's the case, I would recommend contacting a local admin about an edit you want to make.
