just tell your grandmother! she was once a young girl like you that had her first period. you will be surprised how understanding and helpful she is about this major life event. i am sure you will have plenty of questions and hopefully grandma will be able to answer them for you. an understanding school nurse or other healthcare professional would be another source for you. congratulations. having your first menstrual cycle is a milestone in your growth and development. don't be embarrassed.
