Puberty
Premenstrual
During puberty your body will go through many changes, these changes can happen between the ages of 9 to 17, puberty happens over a number of years, as your body changes from a child to an adult. You will grow taller, develop breasts, your hips will become wider, develop a vaginal discharge, start your periods, grow pubic hair under arms and on your vulva (another name for genitals) your skin becomes more oily and you may get spots, you may also notice that you sweat more, resulting in you needing to wash more frequently. These changes are controlled by hormones, these are tiny chemical messengers within your blood.
