Is It Normal for My Period to Come Every 24 Days?

A 24-day cycle can be normal since menstrual cycles naturally vary from person to person.

Explanation

Menstrual cycles can differ in length between individuals. While many people think of a 28-day cycle, cycles that range from 21 to 35 days are considered normal. Having your period every 24 days is within that normal range and may simply be what your body does best. It means that from the start of one period to the start of the next, about 24 days pass. Some people naturally have shorter cycles, and that can be completely healthy as long as you usually experience regular, predictable bleeding. If your cycle length changes suddenly or if you experience other symptoms like severe pain or abnormal bleeding, then it might be good to talk with a healthcare provider. But if you’re consistently having a 24-day cycle and you feel well, there is likely nothing to worry about. Monitoring your cycle using a calendar or an app can help you understand your pattern over time and notice any changes that might require further investigation.
