Hi there Meeka - I remember you!
Yes I am one who still does. I am late 60's and have been taking Utrogestan cyclically for most of the past 15 years, for the same reason - I don't like Utrogestan and the effects of it, and also the potential link with breast cancer of continuous progestogens into older age though no actual causal link has been demonstrated.
So your gynae is wrong - you can take it how you like ie cyclically or continuously provided there is not medical reason specific to you, not to do so.
Obviously no-one chooses to have a bleed at our age for fun, but it's a question of the lesser of two evils.
I was offered the Mirena coil at age 60 because I had some unscheduled spotting but I politely declined. If you do not have abnormal bleeding then no need to.
My only concern would be that with a 7 day regime your uterus lining might thicken but I presume you are having regular scans to check? Also if you've had no abnormal or heavy bleeding this may indicate your lining is not thickeing, and if your oestrogen levels are that low and you are not absorbing much then again - the oestrogen may be insufficient to overstimulate the lining so OK there too?
Hope you're well
