It's common for girls to begin their periods between ages 9 and 18, with the average being around 12. While your daughter being almost 14 without a period doesn't automatically signal a problem, it warrants attention. The fact that she is approaching 15 makes it even more important to seek medical advice.
When to See a Doctor
-
Age 15 without a period: If your daughter hasn't started menstruating by age 15, a visit to the doctor is crucial. ([Source: WebMD, KidsHealth](https://www.webmd.com/children/children-no-period-15, https://kidshealth.org/en/teens/period.html)). This is because, by age 15, 98% of girls have begun menstruating.
-
Three years after breast development: Another important factor is the timeline since breast development began. If more than three years have passed since the onset of breast development and she hasn't started her period, a medical evaluation is also necessary. ([Source: Unlisted source in prompt]).
Possible Reasons for Delayed Menstruation
Several factors can contribute to a delayed onset of menstruation. These include:
-
Hormonal imbalances: Conditions like polycystic ovary syndrome (PCOS) can disrupt hormone production, leading to irregular or absent periods. (Source: Boston Children's Hospital)
-
Thyroid disorders: Problems with the thyroid gland can also affect the menstrual cycle. (Source: University of Rochester Medical Center)
-
Low body weight or intense physical activity: Extreme exercise or being significantly underweight can disrupt the hormonal balance needed for menstruation. (Source: Winchester GP)
Important Note
While many girls experience some variation in the timing of their first period, it's essential to consult a physician if there are concerns. They can perform a thorough evaluation to determine the cause and provide appropriate guidance. Delaying this consultation could potentially delay appropriate interventions if an underlying condition exists.
