Francie - I know a few ladies on Femiston and they are doing really well. I believe the progesterone in Femiston brings fewer side effects than most of the other synthetic ones. If you are feeling good, I'd stick with it - at least for the time being. Yes, Utrogestan is described as "breast friendly" by Dr. Currie and maybe give it a try at some stage. I haven't tried Utrogestan but now I am very post meno I may give it a go. I think one of the problems with Utrogestan is that it needs to be taken on an empty stomach before going to bed and can cause heartburn - some ladies use it vaginally which can effect the bladder (make you go to loo more often). I don't think there is any HRT that doesn't bring some, often small, downsides but the benefits usually make these side effects worth tolerating.
You have been given a low dose HRT and your cancer risk is likely to be very low. Instead of worrying about the risks, think about the benefits to your long term bone & heart health and the improved quality of life you are now experiencing. Enjoy life now. DG xx
