I've had mine for over two years, and didn't have any bleeding at all for the first twelve months.

The last 12 months I've had spotting, not much, and now (at the end of the 2nd year) I'm getting spotting about three days a month, regularly in the last week of the month.

However, I have struggled to lose any weight over the last two years (only lost about 10 kgs when I think I should have lost heaps more) so I might consider getting it removed now to lose some weight.

I don't use it at all for contraception (I'm single!) so it's more the convenience of not having any periods!
