An egg is released from one of your ovaries and the lining in your uterus gets thicker. Over the next couple of days the egg or ova travels down the Fallopian tubes. If it doesn't meet the sperm on its way to the uterus, your body gets rid of the lining and the egg by flushing it out through the vagina. If the ova is meet by sperm then the newly fertilised egg buries itself in the lining and starts growing. Here's a good sight that has a voice over video that explains it in more detail.
