Let's talk ovaries
When I first got my period at the age of 11, I didn't know what was happening to me. We didn't really learn much about menstrual cycles in school, so I wasn't sure what this strange thing happening to me was. I remember calling my mom into the bathroom and asking her what was wrong with me and if I was dying. She started crying, smiled and said, "No sweetie - you have your period." She promptly showed me how to use a pad, and explained when I should change it - you know, typical mother/daughter talk.
