Hello Michele
Really sorry to hear you are struggling on Utrogestan. It is almost bioidentical to our own progesterone, but that doesn't mean it is perfect. I use Utrogestan 100mg, from the 1st-7th of each month. This is Prof Studd's regime, recommended for women who are severely progesterone intolerant (like me). Oddly, I find I am absolutely fine on it some months, then other months I feel just as you describe. The one time I tried it vaginally my symptoms were very severe, so I think it was just too strong for me (you get much more of a hit, taking it vaginally, rather than orally).
So it is worth persevering through to another month, as you might feel totally different next month. Prof Studd is also very relaxed about you not taking Utrogestan some months, if you need a break from the symptoms. I have also seen a specialist meno GP who recommended I went 'long cycle' on Utrogestan, and only take it every third month. I haven't tried that yet.
I hope you feel better really soon x
