and i also want to know what age i will start having periods and stuff like that i even asked my mum she had her's when she was 12 before her 13th birthday ... so please help
ANDY'S ANSWER: Although it is possible to start your period at age 10, it is unlikely. You should look for other signs that puberty has begun, like your breasts starting to grow and the development of pubic and other body hair. You probably have a couple of years to wait before your period shows up.
