Call OnTriggerEnter a frame later

Is there any way to call OnTriggerEnter and wait 1 frame before getting a collision? I'm trying to get if an object is colliding or not with another object right after being instantiated.

My code so far:

 using UnityEngine;
 using System.Collections;
 
 public class ProceduralObjectsChild : MonoBehaviour {

     bool collided = false;
     
     // Use this for initialization
     void Start () {
         StartCoroutine(CheckForCollision());
     }
     
     // Update is called once per frame
     void Update () {
 
     }
     
     void OnTriggerStay(Collider other){
         collided = true;
     }
     
     IEnumerator CheckForCollision(){
         yield return null;
         if(collided){
             SendMessageUpwards("CollisionWithOtherWall", SendMessageOptions.DontRequireReceiver);
         }
         Debug.Log (collided);
     }
 }

The variable "collided" returns always false, where should return true, any ideas?
