In health and puberty lessons (PSHE, health education), menstruation is explained as a normal part of growing up: about once a month, the lining of the womb comes away as blood if there is no pregnancy. It usually begins between ages 8 and 16. Pads, tampons, period pants and menstrual cups are used. Schools in many places provide free period products. Phrases: «the menstrual cycle», «start menstruation», «period pain».
