When will my next period come? When do I need to talk to the doctor about my cycles? Is it normal to have different types of discharge in my underwear? Is it okay if my menstrual cycles aren't regular? Girls have a lot of questions about menstrual cycles and periods-and for good reason. Doctors consider cycles to be a vital sign of health and for many girls (and parents!) puberty can be an especially confusing time because (pre)teen cycles are actually different from what we expect with grown women's cycles. In this text, Christina Valenzuela invites girls aged 12-17 to learn about the intricate, complicated, and important work our bodies do to produce a menstrual cycle through the process of cycle charting. By learning to track and observe periods, cervical fluid, and even basal body temperature, girls can be empowered to "decode" this crucial aspect of health. Guide includes sections on: Basic charting, when cycles first begin Common teen cycle health issues Advanced charting, to look for ovulation Practice charts Options for paper or app charting ... and much more! Cycle Charting for Girls invites preteens and teens to grow in body literacy and self-knowledge through learning to observe their unique menstrual cycle, teaching lifelong skills and instilling respect for the natural design of our bodies.
