Hi jacig1957
I've just skimmed through the replies and if I've not missed anything, you haven't said where in your cycle you were when the scan was done? As you are taking it cyclically and on a very long cycle, you would expect the lining to thicken, perhaps considerably, until immediately after your bleed. If you aren't bleeding and have a thickened lining then this does indicate the utrogestan is not working.
Incidentally, 100 mg utrogestan is the licensed amount for DAILY use in continous combined HRT. It is even less than the licensed dose for cyclical HRT on a 28 day cycle (though on low doses of oestrogen half the amount may work - on a monthly cycle).
I understand your dilemma if you feel so bad on Utrogestan - many of us do - though I can tolerate it just about, - and I am now on around 5 -6 week cycle because my lining was thickening too.
Incidentally, just because your lining is thickening, doesn;t mean to say there is anything sinister, though a thickened lining is the first stage toward endometrial hyperplasia which can lead to cancer, hence it neeeds invesitgating and your lining kept within reasonable limits and not getting thicker and thicker over time.
Also - although 1 pump is supposedly a low dose, absorption varies hugely between women and with different oestrogen delivery methods so you may actually be getting a higher dose than other women - or it might just be that the progesterone dose really is too low as it is far lower than recommended.
As pepperminty said I have previously been given norethisterone tablets - to clear the lining so this is an option - not to be taken for ever, but as a medication, It is a powerful progestogen and can thin down the lining. You may bleed as it thins though I gather not necessarily. Once it has thinned down - and your specialist should be able to recall you for a scan, say after a month, then you could continue but yes you will need to find another progestogen.
Compounded progesterone is not recommended by the British Menopause Society for endometrial protection. Besides being fiendishly expensive and therefore available only to the relatively well off, products are not standardised and therefore have not been tested in proper trials re dosage for that product. Fine for those with progesterone intolerance issues who can afford it but very much off-licence. it is doubtful anyway as sheila says, that this would work for you as your current very low dose is not working.
The key thing is finding somethng you can tolerate that is effective, so you can take it more frequently. Cyclogest doesn't come in pessaries smaller than 200 mg but you could ask your specialist to try that cyclically say for 12 days every two months, after say, a course of norethisterone, if they are open to that? I used ti for several years but was off-licence before utrogestan was licensed for HRT
Some women find that increasing the dose of oestrogen on the days they take utrogestan, prevents some of the sdie effects ike sweating. Sounds counterintuitive, but you would want your lining to be thin first and to be taking a licesned dose or near enough.
I agree with sheila that Mirena coil might be your best option, but then you might want to increase your oestrogen eventually too - and then you will hopefully feel great!
Hope this helps!
