IUD or Novasure?

I have been having trouble with irregular and heavy periods which are also painful so I went to my GP who sent me to hospital for a cystoscopy now I have two choices the Mirena IUD which last for 5 years or Novasure Ablation which is permanent. I have done my research but was curious if any of you have had either procedure done and if you were happy/unhappy? Any feedback would be great!!

I have the mirena coil and on my second one, I find it brill, hardly a period at all and much better pmt. Hope this helps xx
