Key takeaways:

  • The menstrual cycle is the process your body goes through each month as it prepares your body for possible pregnancy
  • If you don’t get pregnant, it results in menstruation (your period)
  • Although 28 days is often thought of as a ‘normal’ cycle, the average menstrual cycle can actually last anywhere from 21-35 days

Knowing your menstrual cycle is a great way to get to know your body, whether you consider yourself well-informed or are just starting out on a journey to better understand your cycle. Here’s everything you need to know about the menstrual cycle, including the different phases, the hormones involved, and how tracking your cycle can help you plan or prevent a pregnancy.
