‘If a man had a period they would be on medication for it,’ says Dr Jan Toledano, co-founder of the London Hormone Clinic. Women put up with mind-shifting, mood-altering, relationship-ruining hormonal issues and yet are meant to just take it on the chin (along with a few hormone-induced hairs). ‘Ah, it’s just your hormones,’ the doctors will say. ‘It’s all part of being a woman!’ But is it? Is it normal to feel so irrationally angry that you want to scream at the poor postman for knocking on the door too loudly? To feel your mood nosedive just before your period begins? To feel the anxiety rise as a hot sweat courses through your veins? For many it’s not until things get really bad that we seek help. But even then, many still suffer in silence.
