I'm 47, my period is still spot on 28 days but much shorter and heavier.
Otherwise I don't know whether I really have any symptoms. I have very occasional hot flashes, like 2 a month but otherwise nothing I could complain about (low mood, aches and pains, searching for words, etc) are definitely menopause related.
Until I started reading up on it I believed HRT was really risky and you'd only take it if your symptoms were unmanageable. Now I see that it has many protective benefits as well as risks.
My GP has minimal ideas about the non symptom benefits of HRT so no point in speaking to him about it.
