Hi there are many different regimes when using Oestrogel and Utrogestan. When I attended a London Menopause Clinic I was told to take between 1-3 pumps of oestrogel (at night) with 100g Utrogestan on a daily basis. In my case I first took the 100mg Utrogestan orally, but found that I was dazed, with headaches due to this method. I then read many of the forums on Menopause Matters and took the 100g Utrogestan via the vaginal route. This also made me a little dazed ( I believe progesterone is cumulative in the body), and I had issues with it irritating my bladder. Some women are on Mr Studd's regime which is estrogel daily and Utrogestan for the first 7 days of the calendar month only, followed by a bleed, (and scans to make sure the womb lining isn't too thick). Some women take 100mg Utrogestan every second night; but I guess this would have to be closely monitored in relation to the oestrogel so that the womb lining remains thin,
It may be best to put 'Utrogestan +Menopause Matters' into a google search; that way it takes you directly to threads.
Hope this helps.
