Most women will continue to have a bleed if they remain on sequential ( cyclical) HRT although a small percentage of women do stop. If you want a no-bleed regime then you will need to go for continuous combined HRT where you take progesterone every day along with the oestrogen. When you change to this you may experience some bleeding or spotting for the first 6 months until it eventually (hopefully) stops - which is normal. This is only suitable if you are post-menopausal otherwise you will bleed when your own cycle breaks through and you ovulate. If you don't know if you are post-meno yet and want to try it - then ask your doc to do so and see what happens.
You would take 100 mg utrogestan each day - although sometimes this is not sufficient to stop bleeding when taken orally with higher doses of oestrogen.
When I took cyclical HRT on a 28 day cycle - by the time I was late 50's the bleeds had stopped so although I was post-menopausal and could have gone to a conti regime, eventually I was able to lengthen the cycle to minimise the amount of time I took the progesterone for ( which I don't like).
