When egg is recieved or fertilised :

The fertilized egg called zygote is planted in uterus and develops into an embryo.
The embryo gets nutrition from the mother’s blood with the help of a special tissue called placenta. It provides a large surface area for the exchange of glucose, oxygen and waste material.
after 9 months birth of baby takes place .

egg is not received or fertilised :

The uterus prepares itself every month to receive fertilized egg.
The lining of the uterus becomes thick and spongy, required to support the embryo.
When fertilisation had not taken place, this lining is not needed any longer.
This lining breaks and comes out through vagina as blood and mucus.
This cycle takes around 28 days every month and called menstruation.
