Misty22, sorry to hear that you are not getting any relief from the Femoston. I was on Angeliq and had very similar problems to yourself, mainly because the oestrogen dose was way too low and the progesterone way too high - a lethal combination for someone like me. Whenever I tried a new HRT product, it always started off well and then it would either stop working due to lack of oestrogen or the progesterone content would build up in my system and cause migraines.
I would suggest you try the higher dose of Femoston first and if that doesn't work, try the Oestrogel/Utrogestan (micronised progesterone best used vaginally) regime. I have been on this regime for 3 years and it is the best I have used by a very long way. This is Professor Studd's tried and tested regime and it might be worth checking out his website.
If you are sensitive to synthetic progesterone in any way and/or suffer with headaches or migraine, I would steer well clear of a Mirena coil. Although most of the progesterone is localised and confined to the womb, enough of it gets into your overall system to cause side effects - breast pain, low mood (while reproductive) and once menopausal, migraine in my case.
The problem many women have with HRT is that the oestrogen component = feeling great with good mood and for many women progesterone component = low mood, breast pain and feeling strange/dreadful - I really wish there was an alternative.
Therefore, if you are at all sensitive to progesterone, you really need to limit its use otherwise it have a drag down effect and ruin all the positive effects of the oestrogen. Sadly, this causes many women to give up on HRT completely which then leads to all sorts of other health problems in both the short term and long term.
I hope that helps.
