Hi Kathleen. As you know I'm a Studd girl using 100mg of Utrogestan, orally, only for 7 days a month. This gives me a regular, light, withdrawal bleed every month with no discomfort. I had a scan in February and my womb lining was nice and thin, and I shall have another in the New Year.
Both Prof Studd and my new GP say this demonstrates the Utrogestan is doing its job properly (and I take twice the amount of oestrogen that you do).
