Hi, I have been using estradiol 100 patches with utrogestan tablets. Saw gp today and changing to Femoston 2/10. I asked when I should start Femoston (would start taking utrogestan tonight) and she said straightaway. However, the leaflet says start taking at the end of the progesterone phase which is the opposite of what she said. I am not that keen to take more utrogestan, is it safe to switch and have 2 more weeks of oestrogen only?
