Hi I am exactly the same. In perimenopause, been on HRT a year, trialed various doses going both up and down again, been using testosterone since June last year and never seemed to find the right balance that works but did feel it had took the edge off the monthly wild swings in moods etc. However last few months my cycle has flipped too and during what would be a high point in the cycle before ovualtion I feel blaoted, irritable, low mood, low libido. Then the last part of the month during the Utrogestan part im much better. This is odd for me as my own progesterone has always been a huge problem, I always suffered horrific PMT and when I first started on HRT Utorgestan didn't agree with me, I hated it and couldn't wait for that part of the cycle to end. Not sure whats causing it but I feel exactly the same as you.
