I would advise against changing your patch weekly (if anyone can even keep a patch on that long) as it will be delivering nothing by the last couple of days, resulting in unstable estradiol levels.
If you have a reason for wanting to reduce your estradiol dose, and progesterone intolerance especially having only ever tried one option is not a good one, then you would be better using half a patch and changing it at the appropriate frequency.
Regarding the utrogestan, this depends what you want to achieve going forward.
If it is causing GI problems I would first think about using it vaginally.
The recommended dose within the NHS is still 100mg daily even if you are only on 25mcg of estradiol.
If you are intending to wean down and come off the hormone therapy completely, again foregoing the long term health benefits should only be considered for a good reason, but if this is your informed choice then you can just ditch the progesterone and taper the estradiol over several weeks.
Endometrial hyperplasia develops over years of unopposed, therapeutically dosed estrogen, not a few weeks.
If you cannot tolerate micronised progesterone either oral or vaginal, then there are multiple other progestogens available as well as tibolone. Nobody needs to lose their estrogen for this reason.
