I'm in the peri-menopause age bracket , and although I have no other indicators of approaching menopause, my memory is becoming scarily appalling. For instance, I can be 100% sure that I've packed something in a bag, only to find that I haven't. This sort of thing is happening quite often, and isn't like me at all. I find myself walking purposefully into a room and them wondering what I'm doing there. Mumsnetters with relevant experience, please help. Am I going dotty or do I need to see a GP about HRT? Is this what menopausal "brain fog" feels like?
