Menarche is the first menstrual cycle, or first menstrual bleeding, in female humans. From both social and medical perspectives, it is often considered the central event of female puberty, as it signals the possibility of fertility.
Girls experience menarche at different ages. The timing of menarche is influenced by female biology, as well as genetic and environmental factors, especially nutritional factors.
Various estimates have placed it at 14 years old.
When You Will Have Your First Period?
When you’ll have your first period depends on how fast you’re developing. Typically, a teenager gets her first period between 12 and 14 years of age. Some girls are early bloomers; others bloom later. Some girls may as early as 9 years old and others won’t have their first period until they’re 16 years of age. If you haven’t had your period by 16 years old, visit your doctor and find out what’s the reasons. In some cases, however, it may still be normal.
How Long Does a Period Last?
A regular period can last between three to seven days. During the teen years, you can bleed for even longer. Some teenagers have their period for 10 days! The length of your period can change from month to month. The heaviness and color of your flow will also change from the beginning of your period to the end. On Day 1, 2, and 3 of your period, it’s normal for your flow to be heavy. Your menstrual bleeding will become lighter and lighter until your period ends.
When You Should Worry about a Missed or Irregular Period?
Missed periods and irregular periods can be normal in teenagers, but you should consult a doctor if you’re a teen and you haven’t had your period for at least three months. This may be a sign of a reproductive problem, like premature ovarian failure.
If you have at least one period within that three month range, you shouldn’t worry. This can be normal, just a byproduct of your fluctuating hormones. Your menstrual cycle will eventually even out, and you will get a normal cycle (although it may not be the perfect 28 day cycle.)
Reasons You May Miss Your Period When You’re Not Pregnant
If you are sexually active and you notice something unusual with your menstrual pattern, there is always a chance that you could be pregnant. Condoms are only 99 percent effective. Birth control pills are only effective if you take them on a regular basis. Skipping a pill can put you at risk for pregnancy.
Other reasons you may experience irregular periods, or missed periods, include excessive exercise, birth control pills, stress, and eating disorders.
– If you’re an athlete, you may notice a change in your menstrual cycle if you’re training super hard or exercising all the time. Excessive exercise can result in less bleeding, fewer periods a year, or your periods may stop completely. In most cases, your periods will return to normal within months after you stop participating in the strenuous sport.
If your period has stopped completely and it’s been over six months, you need to go see your doctor to rule out any medical problems.
Birth Control Pills
– Sometimes, birth control pills are prescribed to help regulate your period. They can, however, cause you to experience a missed period. Hormonal methods of birth control, which contain the hormone progesterone, can cause you to miss your period.
– Whether you’re in middle school or high school, schoolwork can really stress you out, especially if your parents are putting a lot of pressure on you to succeed. Stress is a normal part of life, but a ton of emotional stress can affect your period. Too much stress in your life may cause you to experience missed periods or irregular periods.
– If you have an eating disorder, like anorexia or bulimia, they can slow down your bodily functions and cause your period to stop completely. Please contact a doctor or reach out to an adult if you have an eating disorder.
Weight Gain and Weight Loss
Overweight girls are easier to have irregular periods because there is more hormonal imbalance health issues connected with overweight, such as PCOS (Polycystic Ovary Syndrome.
The underweight girls may have delayed or interrupted periods – being underweight can upset your hormones and stop them working properly. So if your periods haven't started yet, they may be delayed because you're underweight. Or, if you're having periods, they may stop if you're underweight.
Chinese herbal treatment and acupuncture are main treatments for teenager irregular periods.
