No Period Until 15? 5 Possible Reasons!

No periods till 15 years

I remember a girl in my school life who didn’t get her periods until she was 16 years. Each and every girl of the two sections combined was happily (or unhappily) getting their periods between ages 12 or 13, but there was this certain girl who showed no signs of periods at all. While the teachers and especially her mother was concerned, most of the girls used to gossip and some used to make fun of her. While there were ‘agony aunts’ in our class advising her tips on how she can get her period, her close friends who were genuinely concerned about her advised her on going to a doctor. Though it is not a custom where I come from, her mother threw a party after she got her first period. This is an important biological change in every girl’s life signaling that she has entered the child-bearing years and her body is now ready to have a baby.

Today’s post is dedicated to all mothers of teenage daughters and every teenage girl and what you can expect if a girl is having a late period.

By the time a girl reaches 10 years of age, she starts exhibiting signs of puberty. And by the time a girl reaches 15 years of age, most of them have had their periods. But sometimes, there might be a few of them who might not get it yet. In such cases, you must visit your gynaecologist instead of waiting further. Here are some causes your doctor will point out for you being a late bloomer:

Family history

Ask your mother when she had her first period. If she had a late arrival of a period after 15 years or even older, chances are that you might also have your period late for the first time. It is genetic and there is nothing to be worried about. Here are two first signs that will help you estimate well when you might get your period. A girl starts developing her breast 2-3 years before her first period and has vaginal discharge 6-12 months before. After you notice these physical changes, chances are you will get your period soon.

Low weight

A body weight lower than the standard numbers affects hormone levels that prevent periods from happening at the right age. A weight that is 10% less than what is healthy compared to height, messes with hormones and menstruation. Eating disorders like bulimia and anorexia also lead to delayed periods.

Excess weight

If you are obese, you might be on the same boat too. For proper functioning of hormones, your body needs body fat up to a certain range. Too much or too little affects your first menstruation.

Strenuous physical exercise and stress

Too much physical exercise and pushing your body too hard for activities like running or sports can detain your periods till late. It especially happens to ballet dancers and athletes as they train a lot that leaves them with very little body fat.

This combines with a lot of competitive stress, study pressure and other issues. All these combines can be hard on your body delaying your first period.

Certain health conditions and medications

If you have high blood pressure, thyroid, allergies, cancer, PCOS or depression, the medications associated with these prevents periods from occurring at the right age.

If these are none of the issues, talk to your doctor and get an ultrasound test done to check if you have any deformity in your reproductive system. Your gyneacologist is the best person to help you with these.
