Why do girls get periods?

  • Getting your period means that your body has prepared itself to be able to hold a fertilised egg, enabling you to make a baby.
slide5

The Menstrual Cycle

Because all females are different, a cycle can range from 21 to 35 days.

slide6

The period is the beginning of the menstrual cycle.

  • A period occurs because the uterus will shed its lining if an egg (ovum) is not fertilised.
  • A period can be as short as two days or as long as seven.
  • There will approximately be around 2-6 tablespoons of blood lost during each period.
slide7

Your body begins releasing a hormone called oestrogen

  • One of the ovaries releases an egg (one only) and the uterus begins to rebuild its lining.
  • The egg will slowly travel from the ovaries, down the fallopian towards the uterus.
  • If the egg is fertilised by sperm before it arrives in the uterus, a girl will fall pregnant.
slide8

If the egg isn’t fertilised, the uterus wall will continue to thicken.

  • This will cause a drop in hormone levels.
  • The lining will then break down, and another period will begin.
