hi Cee,
reducing the oestrogen may help, with the lining build up and break through bleeding . why not try a trandermal patch? start with the lowest dose 25mcg and see if that helps control the flushes. I started with a 50mcg patch but found that it caused occassional break through bleeding so I gradually reduced the patch size by carefully snipping ( measured) bits off. Am now down to 37.mcg patch ( changed twice weekly) and all is well , for now!
I use urtogestan 100mg every night vaginally , no probs with that either used this way.
hope this info is helpful.
