I was prescribed 2 pumps of Oestrogel (the plan was to adjust and add Utrogestan after a month). I posted a few days about feeling awful on it after trying it for 5 days - completely exhausted beyond belief, unable to function in the afternoons. I had to stop yesterday so I could actually get some work done today and feel SO much better off it (albeit less calm than when on it and with a slight headache). I read something that suggested that in perimenopause oestrogen levels can fluctuate so much that a rapid drop (back to baseline normal levels) can cause menopause symptoms such as hot flashes. So by adding to it I might have had too much hence why I felt MUCH worse on Oestrogel. It is annoying that this is no obvious test that can be done to establish oestrogen levels over levels over time and you are effectively trying to hit a moving target in perimenopause. Has anyone had experience of this issue (have symptoms but feel much worse on eostrogel) and how did you deal with it? Seems pointless to do only one pump which I understand is half of a standard dose? Any thoughts appreciated.
