Yes sammiejane the progestogen in the Mirena is absorbed systemically - just not as much as with contraecptive pills containing an oral dose of the same progestogen. Not sure where you got those figures sammiejane - but you can't compare doses of different progestogens as they behave differently...
Perinowpost - that's interesting...
Ditto stellajane!!! I always hate the cycle when I have to take the prog ( always taken it vaginally) and it always has a sedative effect - I feel like a zombie. Hence the longer cycle. I'm always glad to stop. I don't find it has ever got better over time. I do become accustomed to how I feel on it but once it has cleared by system and the bleed has gone - I feel rejuvenated and full of energy ( except in the mornings
).
