I too am concerned about possible overdosing with progesterone. I have taken last week 'off' as far as my conti patch and stayed with estradiol. I have much less prolapse symptoms, much less fatigue, seem to be getting things done without effort or deliberation. Just functioning basically. But now I need to switch to the conti patch as I was only giving myself an extra week with estradiol. I'm now dreading it as I have a busy week ahead, at the same time I know the importance of progesterone.
I'm intrigued that there may be overdosing of progesterone for some women as I had a feeling my prolapse symptoms came about with hrt and not before, and during the conti phase. I also have had in this last week on estradiol only some 'suggestion' of my body producing it's own progesterone as I've had the feelings I get in this phase of the cycle, just gentler. Relaxed instead of crushing fatigue. Enjoying sugary foods rather than needing them to move..
Hopefully this week I will have communicated with Newson Health or my private local clinic. I finally get it, I am not going to get anywhere with my GP (hate to say that as I had a brilliant GP in the past). Read the Newson and Glynne paper, very interesting.
