After the eggs have been sitting for awhile, use a flashlight and put it on the side of the egg which is not facing you and shine the light through the egg. If you do not see a dark, small object inside the egg then the egg is not fertilized.
Fertilized eggs are available through mail order and also from poultry feed stores. A web search will show hundreds of breeders who will ship eggs. Local area farms will often also have fertilized eggs for sale. Non fertilized eggs can be obtained from grocery stores, local farmers.

Both fertilized and unfertilized eggs have cholesterol.
If you have fertilized eggs you will not have periods, you are pregnant! not much
No. Eggs produced and sold in stores for general consumption are not fertilized and would not contain a forming chick. You could get a fertilized egg from a farmers market stand but hens used to lay eggs for eating are not kept with a rooster.
yes the eggs are fertilized internally
The earliest detection would be through blood labs measuring hormones. That would be after your eggs are fertilized. As for knowing WHEN they are being fertilized, best to err on the safe side and assume they are during unprotected intercourse.
Store bought eggs are never fertilized. If you are looking for fertilized eggs you need to go to a local farm or buy eggs from a hatchery.
Im pretty sure from my experience with slug eggs that snails don't lay eggs when they're unfertilized. They only lay if they've mated and the eggs are fertilized, otherwise (again I know this from slugs, not snails, I could be wrong) they wouldn't lay any in the first place.
If the eggs are laid they are already fertilized. You can go on your porch as long as you pay no mind to them and stay far away from them.
If it is chicken eggs you are talking about you will find that the eggs that are for sale at the market are not fertilised.
