This video is used to teach about menstruation. It's linked in this activity plan.
'One of the physical changes of puberty that a person with a uterus will experience is getting their period as part of what's called the menstrual cycle.
This normally happens between the ages of 8 and 13, and for some people, even older.
Everyone goes through puberty at the time that's right for their body.
Once a person reaches puberty, those with a uterus, prepare for the possibility of eventually making a baby.'
