Copper Coil?

I've had a copper coil fitted for times gone by two months.
Everything seems to be going fine, my lone complaint is that my period seem to be lasting much longer.
I only just wanted to know what other women's experiances are next to the copper coil (NOT mirena coil)
Thanks :D As no one seem to know the answer this is what I found:
Are there any side-effects?
Very emphatically – and you must be aware of these before you resolve to have an IUD.
These devices across the world:

make your period heavier

make them longer

may sort them more painful.

Furthermore, because of the increase contained by menstrual flow, it’s possible that you might become anaemic (‘weak-blooded’).
