Keep going. You can't start wondering about coming off it at this stage. Some people have an easy ride. The rest of us don't. I have recently switched to Estrogel from a compounded cream that had stopped working. My levels are very low. I felt lovely the first day but I haven't felt good since. I expect my depleted body is trying to work out where to put the unusual hormone at the moment. You need to give any new HRT 3 months before reviewing and tweaking with your GP. Leave the testosterone in the cupboard for now and concentrate on the other two. I think you are right to give your body time and to take the progesterone at the point you suggested. This will give you a run of days on the oestrogen alone, which you probably need.
Have you been given Utrogestan for the progesterone part? If so, and if you are worried about it, don't swallow it, just push the capsule as high up your vagina as you can reach. I was worried about it. I'm fine with it this way.
Hormone treatment, especially for those who have become very depleted, is a slow and long process. Believe me, I have hypothyroidism brought on my menopause to deal with at the same time. Another long, slow and very unwell making process!
