Hi my name is Libby and I'm new to the forum I just want some advice on taking my estrogen daily and my utrogestan for 12 days and the confusion between days 15 and 26 all this is new to me having the menopause is driving me mad so that's why I started taking HRT only been on it a week so I don't know any effects of anything at the moment any advice gratefully received my main question is whether I can just take the utrogestan on the 1st of the 12th of the month regardless of how many days are in the month, or do I have to stick to that confusing 28-day cycle. As my periods were still every few months.
