DD(15) is doing GCSE PE. Part of this involves 'personal survival' which takes place in local swimming pool.
The school obv need to book this, can't just turn up, but DD queried what would happen if some of the girls had their period at the time. PE teacher (female) replied that they'd obviously have to use a tampon, they can't miss it, can't arrange another day. A few girls told her they didn't use/get on with tampons and she got annoyed saying they'd have to get on with it on the day as no other option.
