Some women say they knew right away, but there is no scientific way of knowing; other than a blood our urine test.


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.
