When it comes to menstrual cycle length, lots of us get confused about when our cycle begins and ends. So how do you calculate menstrual cycle length like a gynecologist?
The truth is, your menstrual cycle starts on the first day of one period and ends on the first day of the next period. The average menstrual cycle length is around 28 days, but this varies from person to person. Lots of things can affect the length of your cycle. For example, as you get older, your period may come sooner or later or get longer or shorter.
Your cycle can be as short as 21 days or as long as 35 days, and that’s totally healthy. But why do menstrual cycles vary, and what can cause a sudden change in your menstrual cycle length? Hormonal contraception, pregnancy, and menopause can all impact the length of your cycle, but what about your diet, the alcohol you drink, or your work/life balance?
