How to Avoid Loading Admob Interstitial Ad if One is Already Loaded?

I am loading Interstitial ad in baseactivity's oncreate method, This baseactivity is extended by all other activities of the app so every time I start a new activity a new interstitial is being loaded even if there's one loaded already.

private InterstitialAd mInterstitialAd;    @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          createAdhere();  }        public void createAdhere () {            AdRequest adRequest = new AdRequest.Builder().build();            InterstitialAd.load(BaseActivity.this, "ca-app-pub-3940256099942544/8691691433", adRequest, new InterstitialAdLoadCallback() {                @Override              public void onAdLoaded(@NonNull InterstitialAd interstitialAd) {                  Toast.makeText(BaseActivity.this, "Ad Loaded",                          Toast.LENGTH_LONG).show();                  mInterstitialAd = interstitialAd;                  mInterstitialAd.setFullScreenContentCallback(new FullScreenContentCallback(){                      @Override                      public void onAdDismissedFullScreenContent() {                          // Called when fullscreen content is dismissed.                          Toast.makeText(BaseActivity.this, "fullscreen content is dismissed.",                                  Toast.LENGTH_LONG).show();                      }                        @Override                      public void onAdFailedToShowFullScreenContent(AdError adError) {                          // Called when fullscreen content failed to show.                          Toast.makeText(BaseActivity.this, "fullscreen content failed to show.",                                  Toast.LENGTH_LONG).show();                      }                        @Override                      public void onAdShowedFullScreenContent() {                          // Called when fullscreen content is shown.                          // Make sure to set your reference to null so you don't                          // show it a second time.                          mInterstitialAd = null;                          Toast.makeText(BaseActivity.this, "fullscreen content is shown.",                                  Toast.LENGTH_LONG).show();                      }                  });              }                @Override              public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {                  Toast.makeText(BaseActivity.this, "Ad Failed to Load",                          Toast.LENGTH_LONG).show();              }            });        }
