I have no relationship with my parents so no way of finding out when my mother went through menopause. I have no sisters so can't check how old they were when their periods stopped. I'm 48 and my period is still regular like clockwork. I had the coil inserted two years ago and, as predicted by my doctor, my period became heavier. But I'd like to know what peri menopause looks like so I could try and understand if I'm there. Can I get a test done? I don't just want to go and see my GP and waste their time (hardly urgent, is it?). Is there an average age when women become peri menopausal and then menopausal?
