The uterus prepares by creating a special lining for the fertilized egg to attach to and grow. If the egg is not fertilized by the male sperm, then the limning is not needed. The limning and the egg and other material is discharged during the menstrual cycle.

∙ 14y agoWhen you are not on your period the lining of your womb thickens (it is made of blood) and this is the best time to have sex if you want to become pregnant. If you do become pregnant you will miss your period because the lining is needed for the baby to grow. If you don't become pregnant, when your period is due the lining will be 'flushed' out of your body through the vagina. This is why you have a period.
