I agree with eeza- I'd definitely contact the parents first before you even consider doing any sort of education around menstruation. I'd recommend to the parents (and maybe a copy in your room would be good) books like: "The Care and Keeping of You 2" by Cara Patterson, "Personal Hygiene? What's That Got To Do with Me?" by Pat Crissey, "The Body Book" by Nancy Rue, or "Growing up: It's a Girl thing: Straight Talk about First Bras, First Periods, and Your Changing Body" by Mavis Jukes.

Those books can help guide the parents (and you) as to how to approach things around body changes. If you have a nurse or health aid at your school, that would be a good place to refer her.

God luck!
