Why are my periods delayed in teenage years without physical relationship?

Good evening! Delayed periods in teenage girls can occur for various reasons, even without physical relationships. Here are some common factors that can contribute to delayed or irregular periods: 1. Emotional or physical stress, such as exams, changes in routine, or emotional upheavals, can affect hormone levels and delay periods. 2. Extreme changes in diet, rapid weight loss or gain, or conditions like anorexia or bulimia can disrupt the menstrual cycle. 3. A sedentary lifestyle and a lack of physical exercise in routine results in hormonal imbalance. 4. Medical conditions like polycystic ovary syndrome (PCOS), thyroid disorders, etc. If the irregularity persists or is accompanied by severe pain, excessive bleeding, or other concerning symptoms, it's advisable to consult a gynaecologist. They can evaluate your specific situation, conduct any necessary tests, and provide guidance on managing your menstrual health.
