Hi again
Is it possible that your drs are not explaining clearly what's been happening?
As far as I know- and someone may pop along to put me right!- bleeding without using Utrogestan post menopause is not considered a period- it's breakthrough bleeding.
Again, my understanding is that the breakdown of the endometrium which results in a bleed can only happen either with progesterone / synthetic progestogens OR breakthrough bleeding. My understanding is that when we use progesterone / progestogen, it has an effect on the endometrium: it changes the lining from a proliferative phase into a secretory phase where it 'halts' the build up of the lining. When progesterone is no longer being produced (as in a natural cycle or an HRT cycle mimicking this) then the endometrium breaks down and there is a bleed.
I agree with what you have said that your endometrium must be very sensitive to the effects of oestrogen, which is why it's even more important that you find something to offset it.
Has your dr suggested you use Utrogestan vaginally? This is not licensed as such in the UK but many women on here (from my reading) are doing this. If you are seeing a consultant privately (which I assume you are to have regular scans and treatment that is not mainstream) have they suggested this?
Up thread you implied that you were using another sort of progesterone cream that was being prescribed by a dr. Presumably this is in a higher concentration than Serenity because, as someone has already posted, the amount of active ingredient in Serenity does not give endometrial protection.
It might seem a bit illogical to say try 200mgs b of Utrogestan - I can only say what works for me and what doesn't! I get migraines on 100mgs and on 200mgs I don't feel I'm taking anything. If you had no symptoms during your own natural cycles when progesterone would be much higher, it might be worth a try?
I hope you get on okay and find something that helps!
