Can a 16 year old girl go months without period?

Yes. It's not uncommon for a 16-year-old girl to go several months without a menstrual period. During adolescence, the menstrual cycle is often irregular and unpredictable. It's normal to see intervals between periods that are shorter or longer than the average 28-day cycle.

Factors that can contribute to irregular periods in adolescence include:

- Hormonal imbalances that affect the menstrual cycle.

- Insufficient body fat.

- Excessive stress.

- Nutritional deficiencies.

- Chronic illnesses.

- Certain medications, such as oral contraceptives.

If a 16-year-old girl hasn't had a menstrual period for several months and the irregularity persists, it's advisable for her to consult a healthcare professional to determine the cause and ensure it doesn't pose any underlying health concerns. The healthcare provider can recommend appropriate management strategies to address the irregularity.
