HI peri
Definitely not a failure and especially not after trying it for 6 months!!
It is a fallacy that Mirena is not absorbed systemically - it is! I've posted about this several times. The only reason this is stated by gynaes is because as dahiiagirl says it is designed for contraception mainly and if you compare the amount of progestogen abosrbed with an oral POP then the absorption from Mirena is miniscule. However I did do some comparisons a while back and I found that the Mirena at some points ( the amount released decreases gradually the longer it is in place) to be
very approximately equivalent to Femseven combi HRT patches (same "ballpark") in terms of systemic absorption so it's no wonder that some women are sensitive to this. Would need to check this again because it was difficult to work it out from all the figures given!?
Many love it though so still an excellent choice if you are OK with synthetic progestogens. There is the jaydess which is much lower concentration of levonorgestrel but unfortunately has not been tested for its effect on endometrium as part of HRT - this is definitely something that should be done - I agree dahliagirl and peri!!
Peri - glad to hear you are now feeling better.
