Hormonal coil (IUS) and period like cramps

I’ve been using this method for 11 months now upon recommendation of a nurse as I suffer from heavy periods, and the mini pill gives me more trouble than it’s worth. I’ve had cramps before, but nothing like I have experienced with the Mirena coil. I am currently waiting on a hospital appointment for surgery to get it removed as it has gone missing. I was told it was so rare to experience this that it shouldn’t even be of any concern to me, and yet here we are! I have been waiting a month just to be seen to be told it’s missing, always listen to your body ladies!

When first inserted 3 months ago the cramps lasted for about 2-3 weeks inconsistently and occasionally get random ones between cycles, I still get occasional spotting for 1-2 days and periods now last longer than before (originally 3-4 days, now about 4-6 days, sometimes they stop then start again over two weeks). The most frustrating thing is not being able to predict when your period will start, they are getting lighter, but I had hoped they would stop. Also a note on insertion, I know this is all recommended beforehand but make sure you take the pain killers, only local anaesthetic is applied which seemed like it made no difference. You will likely have cramps for at least two weeks or longer whilst it settles down.

The experience is very good in terms of contraception. However I have had quite irregular periods which can be heavy alongside bad cramps.
