Hello. I am on weekly oestrogen patches 50mcg however it does t last so good for a week. I can t reach my doctor to ask so l will ask you. Can l change this patch twice a week or does it need to be lower dose? Because l was told to change it once a week l don t know if l can just go ahead and change it twice a week from now on ? Perhaps l can cut it in half and change each half twice a week. I don t know. Anyone with real knowledge please?
