Hi and welcome
Do search the forum - there are many threads covering bio identical. There is a good deal of confusion about bio identical hormones - virtually all HRTs now have bio identical oestrogen in them but the only bio identical progesterone is Utrogestan which is under ‘micronised progesterone' in the GP's drug book as it's still not considered a standard hrt hormone for some reason and many GPs are not up to speed on treating the menopause. Utrogestan is getting progressively more popular but some, ‘like me', found it more problematic than the other synthetic progesterones. It is important to be open minded about any treatment but especially hrt, as it is trial and error till you find the right regime for you.
Look under TREATMENTs on this site as in the ‘progesterones' section it shows the details about Utrogestan which you could print out and show your GP. Basically you have to gently educate your GP.
Whether this type of hormone therapy works for you will be a matter of ‘trying it to see ‘ as we are all different and most women have to experiment till they find their favourite that gives the least side effects. . DG x
