Hi Kat36, do you mean you are on JUST one third of an Evorel 25 patch, that is, 8.3mcg? Or on one patch PLUS a third, so 33.3mcg?
If on the 8.3mcg that is very very low and, yes, that amount of utrogestan continuously would wash you out! If 33.3mcg, that is still quite low.
I completely understand why the oestrogen is being introduced slowly. I have found that slow introduction and continuous utrogestan have been best for me and my hormonal migraines.
I don't know how you take the utrogestan, but you could try it vaginally. It helps reduce the side effects. It also gives a more consistent dose because it doesn't go through your metabolism.
Your body will adjust to the utrogestan over time and will hopefully be better once you are on, say, 50mcg of oestrogen.
