Hi Masmeno
I have only ever taken conti HRT for a few months but this was on a low dose oestrogen and I had no bleeding - in fact have almsot never had any unscheduled bleeding since I've been taking HRT - for nearly 15 years. I don't like progesterone so I stay with a (long) cycle even in my late 60's, even though I also hate the bleed!
You haven't mentioned what dose of oestrogen you are taking? I am thinking you are possibly on a low dose patch in view of the lack of bleed on cyclical utrogestan? Are you taking the utro orally or vaginally?
One possibility if you think the dose of oestrogen suits you, is to move to a longer cycle if your doc is happy (though if a GP, they may not have sufficient confidence or knowledge to allow this - luckily mine is a gynae specialist so is happy for me to do so). So eg if you took the utrogestan every 6 weeks as I do, then you will have a 4 week period of time on oestrogen alone and reap the benefits. Also the licensed dose is 12 days per 28 day cycle so I take 2 x 100 mg utro capsules vaginally for 12 nights every 6 weeks. Yes I feel foggy-headed and excessivle sleep during this time and often have to get up in the night re bladder, but to me it's a small price to pay for feeling good for the other weeks!
However if you like the continuous progesterone then sounds like this wouldn't be ideal for you. The tricky thing with the unpredictable bleeding is that this is usually an indication that something is wrong so you would not then have the usual warning signs. So if the unscheduled bleeding did not stop after 6 months then this shows that the regime is not really recommended.
I would be interested to hear what your doc says.....
Sorry I can't really help with my experience of this.
