Hi Not really enough info to answer fully.
How far into menopause are you? Are you still having periods? How old are you?
Bit puzzled why you are being given a patch now if you have hyperplasia- is this being prescribed by a gynaecologist?
Was the hyperplasia 'just' heavy periods because you are in peri?
Has the hyperplasia been diagnosed by a scan, a hysteroscopy or both?
According to info online, the treatment of hyperplasia is either the Mirena coil OR a long course of Norethisterone.
It would be unusual to give you HRT containing estrogen if you have active and 'serious' hyperplasia because any estrogen will just build up the lining more. That's probably why you are bleeding.
The guidance on conti HRT is that for women who are post menopause and use it, it can take 3- 6 months for it to work fully and no bleeding to occur.
But if you already have a thickened lining, that's probably not going to work.
