It’s estimated that from our first period to when we experience menopause, women and people who menstruate have around 450 periods. That equates to approximately 6 years of bleeding. And, while you may become accustomed to the length of your menstrual cycle, how heavily you bleed, and your preferred menstrual products, periods are anything but predictable.
The slightest change in your reproductive hormone levels and physical well-being can mean you have two periods in one month, none at all, or more cycle changes going forward. Most of the time, this is nothing to worry about, but it’s worth speaking to your health care professional to put your mind at ease.
We asked the experts to explain the most common reasons why periods change dates, how contraception can affect your cycle and when you should see a doctor.
