Breasts grow
The breasts grow larger (and have the ability to produce milk if a person gives birth). The breasts can be tender when they are growing. Wearing a training bra eases discomfort.
Hips widen
The hips widen to create room in the body to carry a baby if a person chooses to.
Vulva grows
The outer and inner labia and clitoris grow and develop.
Vaginal fluid is produced
The vagina and cervix start to produce a clear white substance that helps clean and moisten the vagina. Vaginal fluid will be noticeable on the underwear. If the vaginal fluid has an odour or is itchy, it could signal an infection and need medical treatment.
