Fertilized Egg?

[michaelinnc84]

I am trying to tell if this egg is fertilized or not. I can't really tell and the picture isn't the best but I thought I would get some thoughts. The store bought egg is just a white dot and my hens egg has a small hole inside the white dot but I just don't know if it is fertile or not.

Thanks for looking.

Photo is blurry but yes if there's a small hole or a ring around the dot, it's fertile.
