Kyleena coil and lower back pain

Kept me from becoming pregnant but at a very high cost... Extreme cramps throughout the month, even after removing the original coil (it was seen to be in the wrong place via ultrasound) and replaced with new one. Pain actually got worse as time went on, after about 8 months I had to get it out as the cramps were debilitating and extreme. I also had a migraine for the first time in my life, and often experienced dizziness and nausea. I also had a patch of recurring thrush infections which was hard to get over as it was so stubborn. The only positive sides were the reduction in bleeding/periods and lack of pregnancy. I will never use a coil again.

I tried the Kyleena coil for nearly 6 months. I previously tried a wide variety of contraception methods but nothing agreed with me. This was the worst one. Even during my sixth month of having it, the pain was like nothing I've experienced before. Very painful during sex. Hot flushes frequently. Heavy bleeding for the majority of the time I had the coil. Awful cramps. Constantly tired to the point I was napping on breaks at work. I'd sleep for 13 hours at a time and still feel tired. The only positive was that my mood didn't seem to change.

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.
