2D Sprite Scroller Shooter - Face Right When Standing still

I'm quite new to coding/Unity and I'm making a horizontal scroller shooter for an school project. My Player animations were all facing direction of movement just fine until I changed x-axis movement in input manager to joystick instead of wasd. Now the Player faces left on default even if I was just moving right.

Is there an easy band-aid fix for this? It's just for a demo, I'm an artist not coder, so if I could insert a line of code that makes the player face right when not moving that would be perfect.

My code is below :)

 // Use Start for initialization

 void Start () {
     rb = GetComponent<Rigidbody2D> ();
     InvokeRepeating ("Shoot", 0.0f, 1.0f / bulletsPerSecond);
     //this is a timer for 5x a second we are calling the function "shoot"
 }

 void Shoot(){
     canShoot = true;
 }

 // Update is called once per frame

 void Update(){
     if (Input.GetButton ("Jump") && canShoot) {
         Vector2 spawnPoint = new Vector2 (transform.position.x, transform.position.y);
         Rigidbody2D bulletInstance = Instantiate (bulletPrefab, spawnPoint, transform.rotation) as Rigidbody2D;
         bulletInstance.AddForce (transform.right * bulletSpeed);
         canShoot = false;
     }

         // X axis
     if (transform.position.x <= -7.61f) {
             transform.position = new Vector2(-7.61f, transform.position.y);


     } else if (transform.position.x >= 20f) {
         transform.position = new Vector2(20f, transform.position.y);
         }

         // Y axis
     if (transform.position.y <= -0.84f) {
         transform.position = new Vector2(transform.position.x, -0.84f);
         } else if (transform.position.y >= -0.01f) {
         transform.position = new Vector2(transform.position.x, -0.01f);
         }

     }


 void FixedUpdate ()
 {
     xSpeed = Input.GetAxis ("Horizontal") * speed;
     ySpeed = Input.GetAxis ("Vertical") * speed;
     rb.velocity = new Vector2 (xSpeed, ySpeed);

 }
