Hi Angel-angie
Two things come to mind. Some women just don't absorb well from patches - so have you had blood tests done (one doesn't say much but having two or three at different points in your cycle should give an indication)? In this case gel might be a better option ( there are regularly women on here changing from patches to gel or gel to patches due to absorption problems)?
The other thing is that I know some gynaes prescribe high dose oestrogen to suppress the cycle and in order to eliminate mood swings. Prof Studd does this I seem to remember - for reproductive depression. Maybe this is the aim of the high dose?
If you have been prescribed this there is no risk and if there was it would have been explained to you. You are less than the natural average age of menopause and so your body would have been making oestrogen for a few more years yet - these years ( until 52) don't count in terms of risk. The evidence is that there is greater risk to your future health from having an early menopause and not replacing oestrogen so try not to worry.
The important thing is to feel well and to find the right treatment that works for you. In your position I think the starting point would be blood tests, in view of the lower doses not working. The other thing is testosterone which can be the missing link for some women. The gynae I saw said that women sometimes make the mistake of increasing oestrogen when it's T they need - although the right dose of oestrogen should eliminate flushes and sweats. The most reliable indicator of of T deficiency is low libido but also tiredness, lethargy, muscle aches/weakness.
What does your menopause specialist say about all of this? You are surely in good hands here.
There is another thread about Provera on here and you could go to the home page of the forum and do a search too. Suunydays and Dana are using it ( these members come to mind but there will be others).
