I've had mine since Nov '03(at my 6 week) and pretty much bled/spotted until my regular periods returned about 2/3 months ago. I've also got the copper IUD, from what I understand it is 'normal', but definitely annoying. My periods also returned super heavy, whereas they were light to moderate before. My midwife said that the bleeding is not abnormal taking into account the IUD and being post partum on top of it. I also remember reading to expect spotting(whatever that may mean) for the first 3-4 months. I told myself I would give it a year to see if I'm happy with it. Even when I don't spot I seem to have a little discharge, not smelly or anything, but enough that I've started wearing pantyliners all the time. All in all I think it's gotten better with time, but I certainly know what you're going thru.
