Pixie I agree, it is frustrating that the combi patch products don't come in a range of doses, but I also agree with the other ladies that the amount of progestogen in them is said to be proportionate to the oestradiol dose. So if you supplement the product with an additional oestradiol source (an oestrogen-only patch/part-patch/oestradiol gel/spray/tablet), you risk getting insufficient protection for the endometrium from an inadequate progestogen dose, which over time could cause potentially harmful proliferation.
Utrogestan was also not a tolerable option for me, nor could I risk an IUD, but there are other progestogens you could perhaps try with standalone oestradiol, such as oral MPA/Provera, Norethisterone tablets & the Dydrogesterone in the combi oral Femoston range. If it's taking Utrogestan orally that could be problematic for you, some women do use it vaginally (off licence) & I believe a few on here are using Cyclogest pessaries as an alternative source of micronised progesterone.
I'm sorry if this isn't what you were hoping to hear as I understand you would prefer to avoid oral progestogens & I think many, many of us sympathise, given the currently inadequate range of options for progesterone & its synthetic variants & the very great problems some of us have with progesterone intolerance.
I hope you manage to find an acceptable solution.
