I think I have started peri because my periods have become more irregular. I'm 45. I have also noticed an increase in anxiety and brain fog ( sometimes a word or a name will not come to me). The only thing I am questioning is the hot flashes. Sometimes if I have a hot drink I feel very warm in my face. It lasts for a few minutes and then goes. This is relatively new to me but not really experiencing anything outside of this. I do not absoutley sweat. Would this be considered a hot flash?
