When I was at school (10 years ago), if you started your period and hadn’t got any materials, there were none provided by the school (or if there were, no one told us) and we couldn’t leave to go to a shop, so had to ask a friend or just keep using a saturated product. I was too embarrassed to change my pad in the school toilets so often wore the same pad all day which was uncomfortable and leaked through onto my trousers and chairs. Me & my friends were so embarrassed of our periods that we didn’t talk about it, even though we were going through the same thing! Not all cubicles had sanitary bins so sometimes you’d remove a product with nowhere to dispose of it. Boys had no understanding of people menstruating.
