Hi Milliepops
When you say you were diagnosed with premature menopause - had your periods stopped for 12 months before you were diagnosed with this, or were you just told you were going throiugh the menopause prematurely, perhpas on the basis of blood tests or something? Normally cycles become erratic initially, as hormone levels start to fluctuate more than normally, and in most women they bceom closer together or you miss a period and the gaps between them become longer until they stop altogether.
If you hadn't stopped your periods for 12 months then you were not yet post-menopause and therefore are still likely to have a cycle - and in this case you should be given sequential (cyclical) HRT which is designed to give a bleed every 4 weeks just as with your normal cycle. You do sometimes get breakthough bleeding but less so than with continuous combined HRT. This is the type you have been given which is why you are getting breakthrough bleeding.
Having said that, even some post-menopausal women get breakthrough bleeding initially on conti HRT as Dancinggirl has said.
If you were not post-menopause I would go back to the doc and ask for cyclical (sequential ) HRT. In your position I would also use separate oestrogen and progesterone so that you can adjust the oestrogen dose to suit - at your age I would want a higher dose of oestrogen. I am on the same dose patches and have been since age 54 approx ie 50 mcg - but you are only 41!
In the meantime do read up as much as you can about menopause using the menu on the left (orange tabs initially, and then green ones) - premature menopause is mentioned here
http://www.menopausematters.co.uk/prematuremenopause.php (read all the sub tabs): and there is an article here which tells you what's going on in your body at peri-menopause
