What is considered as irregular periods?
Most women have between 11 and 13 menstrual periods each year. Bleeding usually lasts around 5 days, but this too can vary, from 2 to 7 days.
When menstruation first starts, it can take up to 2 years to establish a regular cycle. After puberty, most women’s menstruation is regular. The length of time between each period is similar.
However, for some women, the time between periods and the amount of blood shed vary considerably. This is known as irregular menstruation.
The main symptom of irregular menstruation is when the cycle is longer than 35 days, or if it comes more frequently than 21 days.
If there are changes in blood flow, or if clots appear that are more than 2.5 centimeters in diameter, this is also considered irregular.
