What causes my Period?

The menstrual cycle is a series of changes a women’s body goes through every month. Certain stages of this cycle include:

  • Ovulation - when an egg is released by an ovary
  • Hormonal changes - prepare the uterus for pregnancy
  • Menstrual period - the shedding of the lining of the uterus from the vagina if ovulation without fertilization of the egg takes place
    • Menstrual bleeding is variable in women but on average occurs every 21 to 35 days and lasts 2 to 7 days
