Iud copper coil or ius mirena

[me2013]

I'm pregnant with baby no 5 so plan on no more kids my patner wont have the snip as he's a wimp.want something that last years so been look at the coil but not sure which one is best any opinions would be great to hear.

I went for the mirena as it is supposed to make periods lighter (it did) whereas the copper coil is supposed to make periods heavier, longer and more painful.

wouldn't do copper; I've finally had mine removed after 5 years - heavy periods, longer, painful, an although not everyone gets them the side affects in terms of the pre-menstrual activities of bloating, sore boobs etc were far worse, having to chatted to my healthcare prof we both agreed that it would be Mirena next time (if there is to be a next time)
