The term “vacation” generally refers to female menstruation. Generally speaking, 12 years old and 15 years old are in puberty, it is normal to have menstruation at 12 years old, and it is still possible to have menstruation at 15 years old.
Puberty usually begins at age 10 and ends at age 19, and both 12 and 15 are in puberty, a period when most of the body’s organs grow and develop most vigorously. It is normal for women to develop breasts, menstruation, and other secondary sexual characteristics around the age of 12. If you are well nourished and healthy, you can grow taller at 15.
Whether or not you can grow taller at 15 depends on whether or not your epiphyses are closed, so you need to go to the hospital to check the closure of your epiphyses. At the same time, it is necessary to ensure sufficient rest to promote the body’s secretion of growth hormone. It is also necessary to ensure adequate intake of protein, vitamins, calcium, zinc and other nutrients, and regular physical exercise to promote growth and development.
