Another OT IUD question

So, I had the thing put in 10 days ago. I'm still bleeding (ranging from what
I'd call heavy spotting to moderately heavy period-type bleeding.), and some
intermittent cramping. The gyn said I could expect to spot for a few days.
(And the Mirena brochure said I could spot for a few months ...)

How long did you all bleed afterwards? The thing is, I've been having bleeding
problems anyway (and she said it would probably be a few months before the IUD
corrected that), so it's hard to know if this is from the insertion, or just
the same old stuff. (Though [sorry if it's TMI....], the type of bleeding I'm
having seems different from my usual spotting -- both heavier and clottier.
