Why do we have our periods (all the biological facts)?
A period is a natural, normal body process as one’s body matures physically. Simply put: it is when the body releases tissue from the uterus that it no longer needs. It comes out in the form of menstrual blood which has lots of different fluids within it.
A period happens because of changes in hormones in the body. Hormones are chemical messengers. The ovaries release the hormones estrogen and progesterone . These hormones cause the lining of the uterus (or womb) to build up. The built-up lining is ready for a fertilized egg to attach and start developing. If there is no fertilized egg, the 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 most menstruators get their periods around once a month.
