Is it normal for teen girls to have irregular periods?

A lot of people believe that periods are a monthly thing and occur on the same dates every month. But it may not be true in some cases. Even the number of days, the bleeding goes on may be different and not the same for every girl.

As a parent, it might be a concern and you might worry if it is some sort of medical complication. Although, that’s not the case every time. Continue reading ahead to know of irregular periods are normal and what could be the possible causes.

Beginning of Mensuration: The mensuration cycle first starts between the age of 10 to 15 years for most of the girls. It is normal if it starts earlier or a little later. The first period could be a little draining. You may experience back pain, fever, cough and a few more conditions. Your teen might have periods once in two months or for 2 days or the gap between two periods could not be the same and possibly some other issue for the first year of mensuration.

Regular Periods: To understand what irregular periods are, we need to understand what regular periods mean. Regular periods could be described with the help of the menstrual cycle. It means the start of the period is one month and the start of the period for the next month is the same. That means the gap between the two is equal. Girls have their periods after every 24days or 28days or even 34 days for a few. Some girls have different cycle length each month and this could happen for the first few years after her periods have begun.

Ovaries release eggs that have been nested in a thick lining preparing the girl for pregnancy. When these eggs travel in search of sperm and do not find it, it doesn’t get fertilized and starts to fall apart / break which leads to bleeding during which the lining and the egg leave the girls body and the entire cycle known as periods or menstrual cycle. And the first day of her periods is called on Day 1 of the cycle.
