How to fix spite character changing position when turning?

I have a simple movement left and right on my 2d character. My problem is that when it turns/changes direction the character changes position. How can I have my character change direction/turn around while staying in the same position? Any help would be much appreciated!!

 using UnityEngine;
 using System.Collections;
 
 public class playercontroller : MonoBehaviour {
     public float speedForce= 50f;
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
     
         if(Input.GetKey(KeyCode.A))
         {
             GetComponent<Rigidbody2D>().velocity = new Vector2 (-speedForce,GetComponent<Rigidbody2D>().velocity.y);
             transform.localScale = new Vector3(-1,1,1);
         } else if (Input.GetKey(KeyCode.D))
         {
             GetComponent<Rigidbody2D>().velocity = new Vector2 (speedForce,GetComponent<Rigidbody2D>().velocity.y);
             transform.localScale = new Vector3(1,1,1);
         }
         else
             GetComponent<Rigidbody2D>().velocity = new Vector2 (0,GetComponent<Rigidbody2D>().velocity.y);
 
     }
 }
