problem with loading data with serialization in the right time

Hello all,

I made a save system and it works fine but the problem is first health and other data loading then scene is loading so in the new scene my character can`t get the right data. I want to know should I make it work? here is the codes, a collider trigger active the saveData() then it interact with gameManager to save and then a button can load later.

 public class saveLoadData : MonoBehaviour {
 
     gameManager theGM;
 
     // Use this for initialization
     void Awake () {
         theGM = gameManager.instance;
     }
     
     // Update is called once per frame
     void Update () {
 
     }
 
     public void saveData()
     {
         if (!Directory.Exists(Application.dataPath + "SavedGames"))
             Directory.CreateDirectory(Application.dataPath + "/SavedGames");
 
         BinaryFormatter bf = new BinaryFormatter();
 
         FileStream fs = File.Create(Application.dataPath + "/SavedGames/save.db");
 
         saveManager saveManager = new saveManager();
 
         saveManager.currentLevel = theGM.getCurrentLevel();
         saveManager.currentHealth = theGM.getCurrentHealth();
         saveManager.currentRounds = theGM.getCurrentRounds();
 
         bf.Serialize(fs, saveManager);
 
         Debug.Log("Game Saved!");
 
         fs.Close();       
     }
 
     public void loadData()
     {
         if(File.Exists(Application.dataPath + "/SavedGames/save.db"))
         {
             BinaryFormatter bf = new BinaryFormatter();
 
             FileStream fs = File.Open(Application.dataPath + "/SavedGames/save.db", FileMode.Open);
 
             saveManager saveManager = (saveManager)bf.Deserialize(fs);
 
             fs.Close();
 
             theGM.loadLastLevel(saveManager.currentLevel);
             theGM.loadLastHealth(saveManager.currentHealth);
             theGM.loadLastRounds(saveManager.currentRounds);     
         }
         if(!File.Exists(Application.dataPath + "/SavedGames/save.db"))
         {
             Debug.Log("No saved file present!");
         }
     }
 }
 
 [System.Serializable]
 class saveManager
 {
     public int currentLevel;
     public float currentHealth;
     public int currentRounds;
 }

and here is gameManager:

public class gameManager : MonoBehaviour {

 public static gameManager instance;

 playerController myPC;
 playerHealth myPH;

 // Use this for initialization
 void Awake () {
     if(instance == null)
     {
         instance = this;
     }
     else if(instance != this)
     {
         Destroy(gameObject);
     }
 }

 void Start()
 {
     myPC = GameObject.FindGameObjectWithTag("Player").GetComponent<playerController>();
     myPH = GameObject.FindGameObjectWithTag("Player").GetComponent<playerHealth>();
 }

 // Update is called once per frame
 void Update () {
     
 }

 //loading data
 public void loadLastLevel(int x)
 {
     SceneManager.LoadScene(x);
 }

 public void loadLastHealth(float h)
 {
     myPH.currentHealth = h;
     myPH.healthSlider.value = h;
 }

 public void loadLastRounds(int r)
 {
     myPC.remainingRounds = r;
 }

 //getting data
 public int getCurrentLevel()
 {
     return SceneManager.GetActiveScene().buildIndex;
 }

 public float getCurrentHealth()
 {
     return myPH.currentHealth;
 }

 public int getCurrentRounds()
 {
     return myPC.remainingRounds;
 }

}

I am really appreciate for any help
