What is a healthy menstrual cycle length?
You probably learned that the menstrual cycle should last 28 days; however, this isn’t necessarily true. For an adult in fertile age who is not using hormonal birth control and is not postpartum or breastfeeding, anything from 24 to 35 days is considered healthy.
As long as you ovulate.
Twenty-eight days is just the average between 24 and 35, and it’s a standard used to explain things in textbooks simply and easily.
What is important to know is that if your cycle is less than 24 or more than 35 days, OR if you are not ovulating, it’s a sign of a potential imbalance that needs your attention. Some variation is common, but if the cycle is consistently out-of-range, it may be the first noticeable sign that something in your body isn’t quite right.
