Being a teen is a bit of a rollercoaster ride – there's fun and excitement and new discoveries, but also sometimes pain and heartache and period pains.

This is the time in your life when you will most likely experience the greatest amount of change – you could go from young girl with pigtails to a tall young woman.

There are so many decisions to be made about friends, careers, family relationships, boyfriends –and all this while hormones are surging through your body.

This is a tall order for anyone. Health24 takes you on a shortcut about what to expect – even before it happens. And remember to put on your seatbelt before the rollercoaster takes off.
