I am soon to be 46. Since the beginning of April I have been getting my period at 9-12 day intervals. (Normal was 23-27 days) The duration hasn't changed. 2 days, always has been. I'm an emotional mess, gained weight in places I never really had an issue with. I;m not under any added stressors, my diet hasn't changed. I do have an apt with my Dr in a couple of weeks. Peri menopause ???
