Hi Meno42 - you are probably one of the unlucky ladies who is very sensitive to progesterone. This is very challenging. It will be trial and error before you find something that suits you but I would stick with a sequi a HRT so you aren't having progesterone every day. You are young so you do need the HRT - keeping trying things - a good alternative for you might be Oestrogel or oestrogen patches with progesterone, as either Utrogestan or Provera, for 10 days each month - you have to put up with a monthly bleed but there are compromises with any treatment.
Another alternative would be to try having a Mirena fitted ( which delivers progesterone more locally, so fewer side effects) and then use oestrogen as patch or gel alongside.
Do look under TREATMENTS and read up everything on here to get clued up. Print stuff off from this site to show your GP so you can discuss things more effectively at you visit. DG x
