Copper coil (IUD) and lower back pain

Liked the coil however my periods were really long and extremely heavy and I became anemic. My partner could feel it too

The insertion was painful and for the rest of the day I had severe cramps, which paracetamol and ibuprofen didn't help with. I wasn't given any option for pain relief at the time, if I had known it would have been so bad I would have asked whether pain relief was available. After insertion, I went from having manageable periods to very heavy and painful periods (severe cramping particularly on days 2/3 of my period). Naproxen was the only thing that helped to somewhat ease the pain. I persevered thinking it would get better with time, but after 11 months of no improvement I decided to have the copper coil removed. My partner and I also noticed that we would both get very dry and my partner would get cuts on the head of his penis, since removal these have not been an issue. It could be a complete coincidence, but when I asked the nurse removing my coil she said it could be possible... the cuts could have been a result from the dryness or could have been directly from the coil itself (depending on the position of the strings, and they were still quite firm as they take a while to soften). Everyone's body is different and for some this may be a great option (I initially thought it would be due to it being non-hormonal), but I definitely noticed a negative impact on my mental and physical health every month. Since having it removed (2 months ago), I feel a lot better and my periods have pretty much returned to normal.

I loved the copper coil however it caused very heavy and long periods and I had to get it out after 5 months due to anaemia. I also have pmdd so I wanted to try something hormonal to ease this
