Rolling back a transaction will still increment the primary key

I am using Laravel as an API for a ios app.

Now I have setup a DB transaction so that two tables gets created when a user makes an account, one table containing basic info email, password etc, and another table containing some more private info address etc

But I noticed that if I fail the transaction and toggle a rollback() the primary key in the users table will still remain incremented after the rollback. Worth saying is that the foreign key in the user_info table is linked to the primary key in the users table.

Is there any way to also rollback the increment in the table?

My code for testing:

DB::beginTransaction();
    try
    {
         $newUser = User::create([
           'user_type' => $request->input('user_type'),
           'username' => $request->input('username'),
           'email' => $request->input('email'),
           'password' => $request->input('password')
           ]);
    }
    catch (\Exception $e)
    {
        DB::rollback();
        return response()->json(['errors' => $e->getMessage()],400);
    }
    try
    {
         $newUserInfo = UserInfo::create( ['u_info_id' => $newUser->user_id, 'u_state_id' => '2', 'u_city_id' => '7'] );
    }
    catch (\Exception $e)
    {
        DB::rollback();
        return response()->json(['errors' => $e->getMessage()],400);
    }


    DB::commit();
