"Perimenopause" is the term for the years leading up to menopause, a time when women may experience symptoms like changes in their menstrual cycles, moods, sleep, and more, symptoms that, traditionally, haven't been widely spoken about (and can vary considerably from person to person). I know I brought up Labubus, but that doesn't mean I think perimenopause is a trend-its existence is a scientific fact, not something that can be switched out for another keychain.
