da66, welcome to MM!
I'm not surprised you struggled with elleste duet conti because it contains norethisterone which is a synthetic progesterone notorious for causing side effects like breast pain, low mood and it undermines all the good work the oestrogen does.
You did well to read Professor Studd's website, I am one of his patients and I use his preferred regime of Oestrogen/Utrogestan/testosterone and have to say it is the best HRT regime I have used by a very long way. The key it its success is its flexibility and from my own personal experience, the more flexibility you have in your regime, the greater the chance of success i.e. you can easily change the amount of Oestrogel you use and it is very easy to split the dose and take it every 12 hours if you need to in order to keep your oestrogen levels stable.
Utrogestan is a micronised progesterone and again, this is a flexible product because you can reduce your dose if you are progesterone intolerant and also take it vaginally meaning fewer side effects like breast pain because it does not pass through your liver.
Anyone can prescribe this regime for you but in order for it to work properly, it is vital to use the right dosage.
I am currently using 2 pumps of Oestrogel everyday, a small bead of testosterone everyday and 7 x 100mg Utrogestan vaginally every 5 weeks - I am severely progesterone intolerant and this works well for me but you may need a different dose of each product.
I would say it is definitely worth a try.
