When I took Utrogestan I had a withdrawal during the 3 days we're not supposed to take it!
If I remember correctly others on here have said the same. Utrogestan is quite sedating, one of the reasons I had to give it up. If you're otherwise happy with the Utrogestan this might be something that you can help with over- the - counter remedies for the 3 days?
Or maybe the body becomes accustomed, hopefully someone who uses it more than I did will be along.
