Katia, I answered on the other thread and now realise it would have been better to answer on here. If you add a bit of extra oestrogen under the supervision of uterine scans it should be OK. The PIL states you should not add extra oestrogen because of the possibility of womb lining build up but obviously regular uterine scans negate this risk and if a problem was revealed or you started bleeding, you would have to stop.
Progesterone has never helped my libido in fact it is quite the opposite, not least because of having periods. I can't really say whether this new regime is better for libido this stage but it definitely isn't worse! I'm certainly not shedding more hair.
Once this new generation of HRT flies, there will probably be greater variations and doses. Perhaps you will be able to take bazedoxifene with Premarin for example.
