The Lowdown on Periods

Reviewed: July 1, 2021

Periods. We have them for on average 40 years. They give us reason to celebrate, commiserate, and cause endless mood and underwear changes. But how much do we actually know about them, and what can we do to make them easier?

We partnered with Dr Jerilynn Prior – one of the world’s leading experts on the menstrual cycle and women’s hormones – to tell us everything we need to know about our periods.

Jerilynn is an endocrinologist and medical doctor who has spent her career studying menstrual cycles and the effects of the cycle’s changing oestrogen and progesterone hormone levels on women’s health.

In this free webinar, you’ll learn:

  • What exactly is PMS – why it actually happens and what we can do to help
  • Why our periods are different – what causes them to be lighter, heavier and irregular
  • What’s ‘normal’
  • Why we feel period cramps – and how to manage them
  • Why regular periods don’t always tell us we are ovulating
