Hope the move went well!
Sounds like it's probably too early for HRT. Most women absolutely know they are peri-menopausal and have symptoms that they can't cope with before taking the plunge - such as hot flushes, night sweats, maybe dramatically up and down moods including low mood/anxiety, vaginal dryness along with irregular periods!
If you are wondering if it's all in the imagination then probably sounds like you can cope for the time being!!
Just enjoy this stage of life while you can, and deal with menopause when it becomes more noticeable - and certainly if the episodes of chills become more frequent I would get these investigated too.
It's frustrating isn't it, not feeling yourself, but concentrate on making sure your body and health is in the best possible state as you embark on this next stage.
Hopoe that doesn't sound too glib - not meant to be!
