I got my period when I was 12. Thankfully it was a pupil free day but that didn't mean it would go down well. My Mum was at work and my sister at school so I didn't quite realise I had my period yet. I'd learnt all about it at school but I didn't know your first period would be so brown. I showered thinking I was really dirty but it didn't go away.
After two showers, a failed attempt at using a pad, I called my Mum and she told me that when my sister got home she'd show me how to use a pad properly. It was pretty embarrassing.
I was scared to put on a pad and I went through about ten pairs of undies.
