Prescribed estrogel and utrogestan; former daily and latter to be taken 12 days of cycle etc. Feeling relief from some symptoms ie heartburn, general mood, aches and pains , unexplained fatigue, all these vastly improved, all good. However my main symptom that has been driving me CRAZY for a couple years on and off is insomnia accompanied by a rumbling tinnitus during the night that keeps me awake. Alot. Could be pulsatile tinnitus, I don't know. Its like a vibration in my ears. Its worse as soon as my period is over and can last about 10 days, which can mean 10 consecutive nights with barely any sleep. Thats where I'm at right now; 8 nights with just the odd hour here or there. I'm on my knees. However; the 12 nights I was taking the utrogestan I had THE BEST SLEEP EVER and I felt ok too; contrary to other peoples experiences on progesterone treatment. Pre hrt my worst time of the month was the classic 10 days beforeand during my period but now those days are my best! My query is can I, as a still ( slightly erratically) mentruating perimenopausal woman choose to take 1x utrogestan once daily for 24 or whatever days of the month instead of having it 12 days only? I'm thinking it would mean twice as many days of possibly sleeping better. Or is this system of taking utrogestan purely for women who have ceased mentruating entirely? My period still arrives monthly, though I was missing the odd one pre hrt and the cycle varied from 27 to 50ish days if it did arrive.
