Please see your gyno, I started perimenopause at about your age and by 41 my periods had stopped. I was told it (the peri) was 'in my head', just like my IBS, fibromyalgia and incontinence. Everything has resolved in the 2 years since diagnosis and my gyno told me he sees signs my periods may start again. (at 48!) Stay gluten-free and talk to your doctor...
