A period happens because of changes in hormones in the body. Hormones are chemical messengers. The ovaries release female hormones – Estrogen and Progesterone.
These hormones causes the lining of uterus to build up. The build-up lining is ready for a fertilized egg to attach to and start devoloping. If there is no fertilized egg, then lining breaks down and bleeds. Then the same process happens all over again.
It usually takes about a month for the lining to build up, then break down. that is why women get their periods around once a month.
