Hi florriepeck
Obviously only medical investigation can determine the cause of your ongoing bleeding but that is a very high dose of oestrogen for someone of your age. I know we are all different and we don't necessarily want to follow dogma but the "standard" post-menopausal dose of oestrogen on patches (not for younger women who reach menopause early) is 50 mcg. Yes there are different absorption rates so you may need 150 mcg to attain the same levels as another woman on 50 mcg - some needing more to achieve symptom control (eg me!) - but is there are reason why you are on such a high dose?
Also if you've never had any investigation then it would be wise to consult your GP in case there could be reason for ongoing bleeding (eg fibroids or polyps, or thickened lining/endometrial hyperplasia). This is advised in any case for bleeding on conti regime that does not settle after 6 months.
