I suppose my only complaint is trying to work out an escape route for days when sanitary wear needs to be changed. Depending on how heavy a period is, that can be quite often and there really aren't enough gaps in the school day when you're in lower school to make that easy. Also, the toilets are often completely filled because girls need the loo way more often, or to put make-up on, I don't care why, really. Then there's the fun of realising you've started your period in lessons (worst feeling in the world anyway, let alone when you're sitting there in class) and having to work out how to get out of the lesson and to the toilets with a tampon without alerting anyone.
Or is that just me? Might just be me.
