Hi! why do you think that you will require HRT?
Certainly hormone blood tests are reliably un-reliable. Keeping a mood/food/symptom diary may be of use.
Do read the 'bladder issues' and 'vaginal atrophy' threads as this condition needs a different 'type' of treatment.
When I went into peri my periods waxed and waned. Regular for a few weeks, then would disappear for months
. During 2002 I realised that they had gone. Followed by a few months of itchy skin after my bath, as well as cold flushes at night. VA is treated by 'ovestin'.
I wonder why your GP thought you are 'oversensitive' to oestrogen as progesterone is often the Devil in a regime. Let us know how you get on.
