My cycles are still messed up too - and so are my hormones at 11 months post.
Last month was almost 'normal' with very few PMS problems and a regular 8/9 day period but for at least 6 months prior to that I'd been getting the muckiness - sorry, so graphic! - that i used to ger virtually continally with the mirena. It would last for days until my period started, then heavy flow for 4 days, then another 4/5 days of the muckiness again! My cycles would range from 21 days to 36 days!
GGrrrrrrrr!
