Hi Tc
Yes as you say surgical menopause that takes place before you have reached menopause naturally is extremely challenging and shocks the body which takes some time to adjust.
Also true that your oestrogen levels would be cycling - although some maintain that this is not our natural state as we would naturally either be pregnant (very high oestrogen and progesterone levels) or breastfeeding (low hormones). But it is the actual state for most of us (the cycling) for most of our reporductive life.
However whichever is true naturally, post-menopausal oestrogen doses for those who have reached meno at the average age - tend to be lower ie a medium dose and I agree I would want my levels to be higher in your position - not yet at the average age of menopause (can't remember you age?) or at least not at meno before your op.
Also though - adding hormones exogenously (from outside the body) is only a crude approximation of our own enodgenous (internal) hormone production - so is not ideal - as you say there are pulses of hormone production. I don't either form of oestrogen replacement can actually replace this though - but do try patches if you think they will help you feel better?
Interestingly also with most HRT types apart from a couple of tabs maybe, the level is designed to be contstant - which minimises or avoids ( when post-meno) the dramatic fluctuations of peri-menopause - that is the aim. So - if you try to vary it - in this crude way ( the only way ) we have - it may have the reverse effect. For example if you try to cycle to very high oestrogen levels as they would be at ovulation, and then dramatically reduce them eg as they would be just before the natural bleed - maybe this would negatively affect your mood even more?
Some gynaes therefore aim to mainatain a very high oestrogen level (for women eg in your position) - which is only natural in pregnancy ( although the levels are not nearly as high).
Not sure what the answer is but sounds like it is definitely a plan to try to take your levels up a notch - or at least increase the dose until you feel good - irrespective of what the blood results say - but just better to take it steady..
The tricky thing for you though is having to take the prog to protect the womb - and more has to be taken with higher doses of oestrogen - but yes there are quite a few of us who prefer a cycle - even those who have gone through menopause naturally, as continuous progesterone has a sedative and often depressive effect.
Re testosterone - this declines naturally with age but still continues after BSO to some extent as T precursors (eg DHEA) are still produced by the adrenal glands and converted into testosterone in other tissues in the body - but a major source of production is removed at one fell swoop with BSO.
These are just a few thoughts in response to yours and hope it helps a bit
