Each month, the body lines the uterus with a mucous membrane in preparation for a fertilised egg; An egg is detached from one of the ovaries and then heads for the uterus via one of the fallopian tubes. This is called ovulation and it can take a few days. Some women may experience a slight pain during this time, but most don’t notice anything at all. This is the stage where you can fall pregnant, if the egg meets a sperm on its way to the uterus. However, if the egg gets to the uterus without bumping into any sperm, the body disposes of the mucous lining of the uterus to expel the unfertilized egg and fluids. This is what’s known as your period. The period begins and you start to bleed. The average woman will repeat this ovulation cycle about 400 times during her lifetime. After that, the cycle stops for good. This is known as menopause.
