Your period is as individual as your body

  • Modern life has made a big difference to the number of periods we have, mostly because women now eat more and live longer. Fat cells produce more oestrogen, a natural chemical, or 'hormone', that regulates periods. So the richer your diet, the more periods you have, and the greater the flow1.
  • Our eggs are the largest cells in our bodies, and are the only ones that we can see without a microscope2.
  • Periods helped to kick-start mathematics! Scholars think that most early calendars were based on the length of women's menstrual cycles3.
  • We have longer and heavier periods in the colder winter weather4.
  • The modern tampon was invented by Dr. Earle Haas in 1929, and was called a 'catamenial device' or 'monthly device'5.
  • The word 'tampon' comes from the French for 'plug' - literally, a piece of cloth used to fill a hole6.

Every egg in our bodies is created before we are born.
When we're in the womb, we have about 7 million eggs
in our ovaries...
