Health Regen Stop After Damage

Question

I'm working on a health regen system for a game and I'm running into some issues. Seems no one else has tried this as far as I can tell so I HAVE Googled it already.

Anyway I want the system to act like this: When damage is received, wait x seconds and and then start the regen process. If damage is received WHILE regening, stop the regen process and start over.

I can't quite figure out how exactly to do this. Here is my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class HealthScript : MonoBehaviour {
 
     int maxHealth = 100; //Player's Max health
     public float currentHealth; //Player's Current health
     public float regenSpeed; //Regen speed (wait time)
     public float regenWaitTime; //Time before regen starts
     bool isRegen = false; //If regening
     bool canRegen = true; //If can regen
 
     void Start(){
         currentHealth = maxHealth; //Sets player health
     }
     
     void Update () {
         if(currentHealth>maxHealth){
             currentHealth = maxHealth;
         }else if(currentHealth!=maxHealth && !isRegen){ //If they have health less than max
             StartCoroutine(Regen()); //Start regen
         }
     }
 
     //Function for health regen
     IEnumerator Regen(){
         isRegen = true; //Set regenning to true
         yield return new WaitForSeconds(regenWaitTime); //Wait for delay
 
         while(currentHealth<maxHealth){ //Start the regen cycle
                 currentHealth += 1; //Increase health by 1
                 yield return new WaitForSeconds(regenSpeed); //Wait for regen speed
         }
         isRegen = false; //Set regenning to false
     }
 
     //Function for dying
     void Die(){
         Debug.Log(this.name+" died."); //This is where death cycle will go
         canRegen = false;
     }
 
     //Function for taking damage
     public void TakeDamage(float damage){
         if(currentHealth<=0){
             Die();
         }else{
             currentHealth -= damage; //Remove health
         }
     }
 }

You can use StopCoroutine for this, However you will have to store the coroutine in order to stop it, because calling Regen will always return a new IEnumerator. So it isn't the same when u do StopCoroutine(Regen()); and it won't work. You will have to save and use it like so:

 IEnumerator couroutine = Regen();
 StopCoroutine(couroutine);

// Actual code:

     private Coroutine coroutine;
     void Update()
     {
         if (currentHealth > maxHealth)
         {
             currentHealth = maxHealth;
         }
         else if (currentHealth != maxHealth && !isRegen)
         { //If they have health less than max
             coroutine = Regen();
             StartCoroutine(coroutine); //Start regen
         }
     }
     //Function for taking damage
     public void TakeDamage(float damage)
     {
         if (isRegen)
         {
             StopCoroutine(couroutine);
             isRegen = !isRegen;
         }
         if (currentHealth <= 0)
         {
             Die();
         }
         else
         {
             currentHealth -= damage; //Remove health
         }
     }

Yeah. I looked at the stopcoroutine thing but didn't do it right so I figured it just didn't work
