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.

Mirena coil  

I had the Mirena Coil put in for endometriosis. The actual insertion went well because I spoke to my gyno and asked for it to be done in the hospital, meaning that i had the option for general anaesthetic, local anaesthetic or gas and air. I went for the local and gas and air as I had had such a terrible experience having a copper coil put in 5 years prior. The gas and air distracted me and the previous coil removal and new coil insertion wasn’t much bother (i deliriously thanked the team in the room for not giving me as much trauma as the clinic i went to for my copper). The pain after insertion was significant but if you just prepare to have a day or two sat on the sofa taking regular painkillers it’s ok. After the insertion i almost instantly noticed a massive surge of hormones which my gynae had warned me about (she said i might feel ‘weepy’ for up to 6 months as if that isn’t a significant side effect lol). In the end I had major mood swings for around 4 months and was very irritable and all over the place. It did really damage my relationship as it was like i was having PMS every day. I wasn’t depressed or anxious, I just felt like i wasn’t in control of my emotions and i honestly felt like a hormonal teenager who is happy one minute and then angry and upset at something the next. (i also got a bit spotty in the first month or two after insertion - but this cleared up) Eventually after 4 months the mood swings stopped and I can honestly say Mirena is SO WORTH IT if you suffer from endometriosis. It’s completely stopped my endo pain to the point where i don’t even notice my periods anymore. Honestly Mirena gave me my life back within weeks of insertion. After suffering from daily pain for 5 years I now have so much more energy, my chronic fatigue is gone because the pain is completely gone and feel like i’m finally living again. I can make plans, hang out with friends and go into the office regularly - it’s helped me thrive again. It makes me sad that i wasted so many years in pain when this was an option and i would 100% recommend it!! I was initially hesitant to get Mirena because i was worried about the hormones affecting my mood and skin etc as im so susceptible and felt like a different person on the pill. But the important thing is that after the initial hormone “surge” you feel normal again - you just have to wait it out and hope that people around you will be patient with the crazy mood swings for a a few months. If you suffer from endo you will hopefully (everyone’s different) have the silver lining that you’re not in pain anymore so you gain a lot of energy that counters the mood swings. If you have endometriosis or even suspect you might have endometriosis I would really encourage you to get Mirena put in as a first port of call to try and treat it. In terms of my periods they’re SO light - literally just like brown spotting which i barely need a panty liner for which is amazing. sometimes they’re a bit irregular and can last a long time but honestly they’re so light i forget my period exists and Ill confidently wear white trousers whilst menstruating (it’s THAT light) The only reason i’m not giving 5 stars is because several months of feeling absolutely mental is not ideal BUT the level of freedom, energy gained instantly, lightness of period and now lightness of mood now i’m out of the surge period made it all worth it

Mirena coil  

I generally had an okay time with it but i kept getting spotting/or a light period every couple of weeks. much lighter than a normal period would be and without the usual pain i would get but definitely more frequently - which i found frustrating, and was often very bloated because i was so regularly getting a short period, it was quite annoying, so i stopped. I also thought it was making my hair shed. it was always pretty uncomfortable putting it in

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.

Mirena coil  

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.

Mirena coil  

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.

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!
