Mirena coil  

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!

Mirena coil  

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.

Benilexa coil  

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.

Benilexa coil  

I previously had the copper coil for 4 years because I wasn't keen on using a hormonal contraception but I wish I'd changed to benelixa sooner. I opted for a numbing injection during the procedure and hardly felt anything, it was great. Afterwards there was some very mild cramping and unfortunately I did get mild thrush within the week, however since then it's been amazing. Hardly any pain during periods and they are sooo much lighter. I used to bloat all the time but now I never do. I also lost about 4lbs and have stayed at that weight ever since. I had thinning hair previously and now have lots of new baby hairs coming in all over my head which I'm delighted about. Sex drive has decreased ever so slightly but not enough to be a problem. No changes to my skin or any other negative side effects. Really can't recommend it more, I'm delighted with not being in agony every month and I have much more energy since I'm only losing about a quarter of blood compared to before.

Benilexa coil  

I was told to take painkillers (paracetamol & ibuprofen) before the procedure which I did. For the procedure I had two lovely ladies who were supportive and talked me through all of the steps. I was offered pain relief including gas and air, so all of that was great. What I didn’t realise was the “bad period cramps” you are warned about were actually more like mild contractions, and having had a traumatic miscarriage a few years ago. The coil fitting unfortunately ended up triggering this trauma along with my anxiety, when I spoke to my GP they mentioned it was PTSD and that this can happen after a coil fitting. Afterwards the coil felt really uncomfortable for about 4 weeks where I could feel it inside me all the time and sometime it felt like it was scratching around in there! Also certain exercise & stretches were uncomfortable & often aggravated it leaving me in pain. My hormones were also all over the place on week 3 but that passed fairly quickly. I’ve had great support from the clinic and was referred to have an ultrasound to confirm it was in the correct place. On a more positive note I’ve only had one heavy bleed a week after it’d been fitted and no further bleeds and so far only spotting once. It’s now 11 months later and things have settled, so this is now working for me which is a relief.

Not 100% sure what to think yet. Enjoying not having to worry about administrating my contraception as it’s in there and working. However I am having unpredictable spotting, some emotional mood swings and often being bloated.
