Menstruation is usually irregular within 2-3 years after the onset of menarche because the ovaries are just beginning to ovulate, and the cycles may not be very regular, so there is usually no need to worry.
However, if there has been sexual intercourse, it is important to take a pregnancy test.

More Info

Missed periods after the onset of menstruation can be concerning, especially if you have recently started menstruating. It is not uncommon for young individuals to experience irregular menstrual cycles in the first few years after menarche (the first menstrual period). This irregularity can be attributed to a variety of factors, including hormonal fluctuations, stress, changes in weight, and lifestyle factors.

Understanding Menstrual Irregularities
1. Hormonal Changes: The menstrual cycle is regulated by hormones, and it can take time for the body to establish a regular pattern. During the first few years after menarche, it is normal for cycles to be irregular as the body adjusts to the hormonal changes.

2. Stress and Lifestyle: High levels of stress, significant changes in weight (either gain or loss), and changes in physical activity can all impact menstrual regularity. Stress can affect the hypothalamus, which plays a crucial role in regulating the menstrual cycle.

3. Health Conditions: Certain health conditions, such as polycystic ovary syndrome (PCOS), thyroid disorders, and other hormonal imbalances, can lead to missed periods. If you have other symptoms, such as excessive hair growth, acne, or weight changes, it may be worth discussing these with a healthcare provider.

What to Do Next
1. Monitor Your Cycle: Keep track of your menstrual cycle, noting any changes in flow, duration, and symptoms. This information can be helpful for your healthcare provider.

2. Consider Lifestyle Factors: Evaluate your lifestyle for any significant changes that may have occurred around the time your periods became irregular. This includes stress levels, diet, exercise, and sleep patterns.

3. Consult a Healthcare Provider: If you have missed your period for three months, it is advisable to consult a healthcare provider. They can perform a thorough evaluation, which may include a physical examination, blood tests to check hormone levels, and possibly imaging studies if necessary.

4. Pregnancy Test: If there is any chance you could be pregnant, it is essential to take a pregnancy test. A missed period is one of the first signs of pregnancy.

5. Discuss Concerns: If you have concerns about your menstrual health or if you experience other symptoms (such as severe pain, unusual discharge, or significant weight changes), make sure to discuss these with your healthcare provider.

Conclusion
While it is not uncommon for young individuals to experience missed periods after their first menstruation, it is essential to monitor your health and seek medical advice if the irregularity persists. Your healthcare provider can help identify any underlying issues and provide guidance on how to manage your menstrual health effectively. Remember, every individual is different, and what is normal for one person may not be for another. Taking proactive steps to understand your body and seeking help when needed is crucial for maintaining your overall health.
