Periods became heavy which was expected but cramping after insertion was incredibly painful and I was not prepared for the level for pain. I required A&E support with pain relief and examination to ensure it hadn't moved or perforated. The monthly pain had me missing work, almost fainting and squirming in pain. I had to learn pain management every month to be able to work effectively. Around 1 year later I felt in control but around 3.5 years I have experienced even heavier periods and more pain. I felt determined to make this method work as I didn't want to use hormonal contraception again. Cramping and heavy bleeding caused nausea, extreme fatigue and ovulation cramps. Overall, I experienced a lot of discomfort and only a few days out of the month where I felt well. I recently got told my iron stores are VERY low and that explains a lot of the worsening menstruation symptoms due to losing too much blood per month from the copper coil. I'm not going to scored it as terrible as I know others have had no issues using the copper coil and there were times when I felt in control of it. Maybe my age and change in hormones have made my symptoms worse? Or it just sucks, I don't know. Take ibuprofen and paracetamol before your insertion as this will help a lot!!

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 got pregnant because my copper coil moved down towards my cervix. Could still feel the strings as normal. For 4 months prior to that I'd been having symptoms of vaginitis (dry feeling during sex without actually being dry and stinging during urination). The doctors told me it couldn't be the coil causing it but I now believe it was, instead they treated me for uti and yeast infection and dermatitis (none of which I actually had). So yeah I suffered pain for 4 months and then got pregnant. I wouldn't recommend because it's so hard to tell it moved, if you get symptoms of vaginitis or vaginal irritation ask for an ultrasound. Getting pregnant at 20 and then having to terminate the pregnancy is traumatic.

Works well for me, was hoping would take away periods altogether but definitely made them lighter. Found fitting comfortable as just had some cramping. But I have quite a low cervix, so I could feel the strings and needed them trimmed.

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.

Prior to having the mirena coil I had the most horrific periods literally to the point of passing out. I can say I have had my coil in for nearly 6 years and not had a period since and now I feel like I have my life back! It has been one of the decisions I have ever made and also hardly had any hormonal side effects.

I loved the mirena but over 3 different coils, shortly after insertion I would get kidney infections that didn’t respond to antibiotics. The link was only made on the third despite me asking the gyno about it. Such a shame because I loved it otherwise. Kidney infections mostly skipped the uti stage and went straight to them but bacteria wouldn’t grow in pee. If this sounds like you remove it!

Had it inserted at birth during a c section so no pain for insertion. Periods for lighter every month with significantly less pain than before and have virtually stopped after 8 months - just a small amount of spotting.

I got the Benilexa IUS to treat painful periods and PMS. However, within under two months, it severely exacerbated my PMS, causing sleep deprivation, frequent panic attacks, bouts of crying, and increased suicidal thoughts. This was also experienced during my period. Most importantly, it has completely disrupted my Psoriatic Arthritis management. Despite being on a biologic (adalimumab), the IUD has triggered a massive flare in my right foot that has now progressed to my left foot and ankle. I went from rarely needing NSAIDs to relying on daily ibuprofen. Regarding my psoriasis, I noticed a slight change in dryness/thickness in scales but not much else. My periods were even more awful than before and I had to call sick into work which l've never had to do. I further experienced fluctuating pelvic and ovary pain, with some days better than others. I expected side effects, but not to this extreme, system-wide level. I understand for some women the IUS is life changing in a positive way and a great treatment for endometriosis, etc. However, for other women, it may not be suitable for our body, especially if you have pre-existing conditions like myself. Whether that's due to the small amount of hormones released into the blood stream or the body reacting to a foreign object to the body. Or even both. Please do your research and consult with professionals if you have specific conditions or autoimmune diseases. Because most of the time, they won’t or care to understand your concerns. I've thankfully had it taken out today and was told by the GP it would take a few weeks to see a positive adjustment, flare reduction, and difference to body/mind, to my joints especially. You know your body best, any triggers and what helps. If you have a terrible experience like mine, don't let anyone tell you to put up with the lUS a few more months just to see if it "settles", etc. Advocate for yourself and try all avenues. I’m lucky my threads today were visible as they were not at the last GP appt. And I’m very grateful I had a caring and understanding GP who listened, affirmed my concerns (such as assessing my joints), and believed me.
