Short Menstrual Cycles: What's Normal & When to See a Doctor

It is not typical to experience a menstrual cycle that is only 17 days apart. The average menstrual cycle is between 24 and 38 days, with the majority of women having a cycle that is between 28 and 32 days. If your menstrual cycle is consistently shorter than 24 days, it is recommended that you speak with a healthcare provider to determine if there is an underlying medical condition causing this.
