📚 Understanding Normal vs. Irregular Periods
Let's break down the difference between normal and irregular menstrual cycles. Knowing the characteristics of each can help you better understand your body and when to seek medical advice. A regular cycle is predictable, while an irregular cycle has variations in length and flow.
Definition of a Normal Period
A normal menstrual cycle typically lasts between 21 and 35 days, with bleeding lasting from 2 to 7 days. The flow is generally consistent from month to month, and you can usually predict when your next period will start with reasonable accuracy.
Definition of an Irregular Period
An irregular menstrual cycle is characterized by variations in cycle length, flow, and duration of bleeding. This can include cycles shorter than 21 days or longer than 35 days, missed periods, or significant changes in the amount of bleeding from one period to the next. It's also called oligomenorrhea, menorrhagia, or metrorrhagia.
