You still have a chance. Once an egg is fertilized it starts to make something called Early Pregnancy Factor to let your body know that it's on its way. So your body will hold off as long as it can before letting AF show up due to this. That doesn't mean that the egg will knock about in there until it can find a good place to implant, but it does buy the egg, if its been fertilized, a little bit more time. Good luck!
