When menarche occurs
Most women experience menarche between the ages of 10 and 15.
On average, young women experience menarche at about 10 to 15 years of age, sometime during the last few years of elementary school to starting middle school. However everyone differs as to when they first experience their period. Some experience it as early as 8, and some may not yet have had one by the age of 16. It all depends on the physical and psychological condition of the individual.
Moms, let your girls know about it in advance!
Mothers may want to tell their daughters about menarche in advance so that it will not scare them when sudden bleeding starts. If your little girl seems to be getting tall all of a sudden, or her breasts become more noticeable, you can expect it to begin any time. Suggest that she keep a few sanitary pads and a pair of sanitary panties in her purse to carry with her, so she is well prepared when the time comes. Please remember to congratulate your daughter when she has her first period. Make sure she knows it is a wonderful change to embrace and nothing to worry about.
Menstrual cycles take about 3 years to become periodical
After menarche, menstrual cycles tend to be irregular at first due to hormone imbalances. Some, of course, may have a monthly period right away, but it commonly takes about three years before a young woman's menstrual cycle becomes consistent. Young people are likely to experience physical and psychological difficulties during adolescence, which result in irregular periods. Don't worry, just be there for her. If you are still worried about your daughter having irregular periods, you should chart her basal body temperature using a basal thermometer, and bring the information with you when you see a gynecologist.
If menarche does not occur
While its timing differs for each person, you may want to go see a gynecologist if there is no sign of your daughter having her period after she has reached 16 years of age. It is also a good idea to see a doctor if her periods do not settle into a regular pattern about three years after menarche, tending to last longer than ten days or to be absent for over two months, for example.
Many adolescents are also interested in dieting, however inappropriate dieting can cause amenorrhea or anemia. So please make sure that she maintains a healthy diet.
