During puberty our bodies go through all sorts of changes, these changes are like little signals that your periods might be starting soon, such as:

• Growth of under arm and pubic hair
• Hips widen and breasts grow and may be tender
• You might find you're sweating more
• Your skin and hair may get greasier and spots can appear
• There may be discharge in your underwear, that is creamy or yellow in colour
• You might have mood swings – one minute you're up the next you're down!

These changes don't happen to everyone at the same time, so don't worry if you develop sooner or later than your friends. Whatever happens to you it's important to remember that everyone's different and it's all perfectly normal.
