Some women say they knew right away, but there is no scientific way of knowing; other than a blood our urine test.
ANSWER
Actually, there is no scientific way of knowing if an egg is fertilized. Obviously, if you become pregnant then an egg did get fertilized but pregnancy does not always occur. I have read that anywhere from 40-80% of fertilized eggs not not actually implant and are just passed in the woman's period. In this case your egg could have been fertilized and you would never know it.

No, they bleed during implantation. When the egg is fertilized, it happens in the space of the fallopian tube. In a sense, the body doesn't "know" there's a fertilized egg until implantation occurs. There are no signs of fertilization before implantation.
Yes, it is possible to have an upset stomach the moment your egg has been fertilized. A pregnancy test will be the only way to know for sure if you are pregnant.

A fertilized egg implants into the Uterus.
The sperm doesn't have to. Once the egg is fertilized it stays fertilized.
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.

A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
