Hormonal coil (IUS) and spotting

Initial 3 month settling in period is intense, lots of bleeding and emotional side effects plus insertion pain. After 3 months it settled and I thought I had found the holy grail, emotionally stable and no side effects. At 6 months I developed a large ovarian cyst which put me in agony and A&E, doctors said this was caused by the coil and had to remove it. Unfortunately I cant recommend, the search continues.

Sex drive plummeted on this, plus I think it made doggy uncomfortable and even painful, never had that issue before! I also had breakthrough bleeding whenever I did have sex, although this was the only time I would bleed. I had more intense period cramps and sore breasts on this than I had on any other contraception (implant, combined pill and mini pill), and I'm so glad to have it gone! Absolutely horrific experience getting it in, and ended up getting it out by myself at home when the sexual health nurse didn't want to remove it. Thankfully it was barely even uncomfortable to remove (would still recommend going to a health professional to remove though just in case!).

I've had the mirena coil for four months, I'm still bleeding irregularly (period every 8 days) and lots of spotting. I've been dizzy for months, I'm feeling very low, I have water retention and a lot of lower back pain that feels like a pinched nerve so I'm battling to concentrate on work. I really want to have it removed but I'm terrified of going back to the alternative of extreme heavy periods that made me anemic.
