I'd put money on your uterus building its lining in response to stopping tibolone and also to starting oestrogen, both these will build up the lining, then the progesterone is to help it not build much and to shed itself.
Why did they take you off tibolone when you felt well with that?
I'm 53 and I'm booked for a scan 28 days after my last period started, to determine if I'm allowed tibolone or not. They said to come for my scan whether I've started bleeding or not, which I was planning to do anyway. My periods vary from 24 days to 34 days apart and ignore when I take progesterone for 12 days.
The only other time the lining was measured, it was 6mm in my mid thirties, so 5.5mm sounds ok to me.
If the lining is thin, just
before my normally
very heavy period is due, then I can have tibolone to trial, but if my blood pressure rises I have to stop it again. My blood pressure always rises if I'm short of oestrogen, so all in all I don't think I'm getting it
