Mirena coil and irregular periods

Have only had the coil for 2 months (although feels like much longer) so will give it a bit more of a chance, I also acknowledge that everyone reacts differently and my side effects seem to be less common, however in my experience and at this point in time, the negative side effects FAR outweigh the positives. My GP talked me into trying Mirena for managing my PCOS and the excruciating pain I would experience on occasion from burst ovarian cysts, as well as the birth control aspect. I’ve gone from an abnormally long (but fairly painless) cycle to an even longer one, bleeding and in moderate-severe pain almost daily. If my stomach doesn’t hurt, my head will be, or both. I’m not joking when I say I look pregnant from abdominal swelling on top of it all.

I've had the Mirena coil for about 10 months now, my doctor recommended it to stop uterine polyps from reappearing. Prior to the coil I had very heavy, extremely painful periods and pretty bad iron deficiency, but now my periods are super light and not painful at all!! The insertion was painful but not worse that the period cramps I used to get before; I spotted for 3 months straight but after that I started having semi-regular periods. I noticed that I had much more energy (probably because my iron levels were back to normal), my libido increased and I lost weight. I am really really happy with the coil.

I swapped to the coil as I started getting migraines on the combined pill and wanted a longer term solution GP advised to give the coil 6 months to settle in but during that time my skin has gradually got worse with bad acne, I still have periods which are lighter granted but lasting 8-9 days, much worse periods cramps than on combined and then for last 2 months spotting almost everyday and bad period like cramping. GP thought these symptoms suggested coil displacement but USS confirmed it was in situ and these must just be the side effects I personally get from mirena. The cramping and constant spotting and acne is affecting my sex life and general mood day to day so trying to get the coil removed and tempted to try the copper coil (although I went for the Mirena as I’d read you can get the symptoms I’m currently having on the copper but only time will tell!)
