Ive had it since Aug of 07 and I feel like I am spotting atleast 2 wks out of the month. The cramps suck and I think it is different for everyone, I do feel like even my spotting is getting less each time so I hope for me it will stop soon. Good Luck! you just have to deal with it and it SUCKS!!!!
I got my IUD in October 08 while on my period. My cramping only lasted a day or two and my spotting only lasted a handful of days. In November I got my period at the normal time but it was much lighter and in December I didn't have one at all.
