2D Camera Follow boundaries

alright so I'm trying to create a Camera that follows the player until it hits the edge of the map in which case it will stay inside the scene, I watched a video on it and the yAxis boundaries are good, but the xAxis boundaries are stopping too soon from the actual xAxis border.

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class CameraFollow : MonoBehaviour {

 public Transform followTransform;
 public BoxCollider2D MapBounds;

 private float xMin, xMax, yMin, yMax;
 private float camX, camY;
 private float camOrthsize;
 private float cameraRatio;
 private Camera MainCam;



 private void Start()
 {
     xMin = MapBounds.bounds.min.x;
     xMax = MapBounds.bounds.max.x;
     yMin = MapBounds.bounds.min.y;
     yMax = MapBounds.bounds.max.y;
     MainCam = GetComponent<Camera>();
     camOrthsize = MainCam.orthographicSize;
     cameraRatio = (xMax + camOrthsize) / 2.0f;
 }
 
 
 void FixedUpdate()
 {
     camY = Mathf.Clamp(followTransform.position.y, yMin + camOrthsize, yMax - camOrthsize);
     camX = Mathf.Clamp(followTransform.position.x, xMin + cameraRatio, xMax - cameraRatio);
     this.transform.position = new Vector3(camX, camY, this.transform.position.z);

 }

}
