ANSWER
When the egg is not fertilized, it is shredded off from the body and menstrual cycle takes place. Ovary releases one egg every month. At the same time, the uterus also prepares itself to receive a fertilized egg. The endometrium lining becomes thick and spongy for carrying embryo. It would also nourish the embryo if had fertilization taken place. IF the egg is not fertilized, this lining breaks. This results in the discharge of blood and mucous through vagina. This menstrual cycle last for around 5 to 7 days until all the debris of endometrium along with blood is discharged.

Answer:
In a female human, ovulation occurs once in a month. The uterus is starting to prepare itself to receive the fertilized egg. It grows thick, muscular and rich in blood and tissues.
When the egg is not fertilized, the thick uterus lining breaks down. The blood, tissues and the non-fertilized egg come out of the vagina as menstruation.
