Periods. Ah periods. Rarely a month goes by when I don’t dread its arrival. And I’m pretty sure that most women (and some men) feel the same as I do. I grew up thinking it would be like the adverts on TV but while I don’t skydive when it’s my time of the month I have been programmed to have a fixed smile (more of a grimace) on my face and tell no one what’s happening.
