Changed from mini-pill after 16 years as I wanted to know my body without hormones and start to understand my cycle better. No issues with the copper IUD. My periods are a bit heavier but they are more predictable and regular. I do have more cramps but they are manageable. Insertion was fine, just uncomfortable. I was surprised how quickly the cramping started after though. I was in quite a bit of pain for an about a week as it settled in.

I genuinely love my copper coil (IUD) that lasts 10 years, and I wanted to write this review as I used to hear horror stories about it and it almost put me off, but I didn't experience this and I want to reassure others that may be considering this. I got my copper coil in March 2023 after an unwanted pregnancy as a last resort. No hormonal contraception worked for me and I often experienced negative side effects, so I felt my last attempt was the copper coil. What a GREAT choice! Yes, the insertion is uncomfortable, but I asked for cervical numbing cream and it was mildly uncomfortable for two minutes. Definitely bearable with numbing cream. Since then, my periods are still regular a little bit heavier. and I do get a few more cramps. Very easily managed with a menstrual cup and painkillers. I love not having to think about my contraception, and I don't need to think about getting it replaced for TEN years. What a dream! It's a life saver for those of us that struggle with hormonal contraceptives.

As the copper IUD gets so much negative press I wanted to post my genuine positive experience. Initially I was apprehensive to get the coil after hearing so much fear mongering, and so many users saying they had major cramping (perhaps some did), but this wasn't the case for me. I experienced the worst period cramps that I have ever had within the first 7-10 days post-insertion, but it was manageable with ibuprofen + heating pad. Once I got through those initial days it practically subsided (apart from the slight numbness around my cervix from the procedure which healed around the month marker so I recommend taking any kind of sex slowly to avoid worsening it). Between days 10 and my first period I had occasional mild cramps here and there, but after that first period the cramps completely subsided. Fast forward to month 6 I can confidently say that the cramps only occur at normal times of the month (just before or the first days of your period) just slightly more painful but not unbearable. When it came to bleeding side-effects in the first 3 months I never got any spotting between periods and my period came on time but was heavier than usual (more bleeding but the same number of days as without an IUD). However after that 3 month marker I remember the bleeding becoming lighter, to the point now where it is similar if not the same as the amount pre-IUD. In conclusion the IUD has worked great for me, and I barely even notice it now. If you can do visit a sexual health clinic over a GP surgery, as they seem to be more experienced. Please don't let peoples bad experiences put you off, I strongly believe that for 99% of IUD users the bad experiences are based upon people noticing the fine details with their body that perhaps was there before but now that they have the IUD they become a 'worrier'. That every little cramp means something bad. I say that if you have an issue, go and see a professional who's qualified and not ask the internet.

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.

I’ve had the kyleena iud for just over a year. Initially, I had more painful periods but that’s common for about 6 months as your body adjusts but this has since gone away. After about 6 months, I started to suffer with vaginal dryness. This was easily managed with lube during sex but after a year it really started to get bad. It was causing constant thrust (5 times in 3 months) which I had never been prone to before and the pain during sex can sometimes mean we have to stop or I’ll be okay for a bit but then after will be bleeding or have sort of friction burns. It’s coming out soon but it’s just a shame about the dryness as I loved it otherwise

My first year of the coil seemed to be okay. Took a while to get used to and on the grand scheme of things after about 3 months my period pretty much left.. but in the last year, I’ve been getting symptoms of anger, forgetfulness and generally feeling checked out. Going to speak to GP to find another option.

Kyleena was recommended with mr having Adenomyosis due to wrongly being given the copper coil before and bleeding for months on end. Kyleena had irregular periods to begin, the only sidr effect for the first 4 months were severe coldnesd/flu like symptoms the day before my period for all 4 months. As my periods stopped, my sex drive and mental health crashed. I'm on month 9 and awaiting removal.

Having used the pill on and off for 20 years I was hesitant to use another hormonal contraception but I was so happy with kyleena - no noticeable mentsl or physical symptoms. Insertion is not pleasant but it's over in seconds.i experienced some period cramps in first few weeks but then periods became extremely light and pain free for the last 3-4 years. I would get this method again without hesitation.

I had a terrible experience with Mirena. It started with severe cramping after insertion. The cramping continued for weeks. I got a UTI from it. Then the other symptoms started - severe depression, sneezing, severe sinus pain, insomnia. I experienced severe vaginal dryness and vulvodynia (shooting pain down there) which ultimately led me to showing up at my gp and begging for it to be removed.

Periods stopped, no noticeable side effects other than toward the end of the 5 years when I had a few side effects (tender breasts, spots, mood swings) which I put down to hormonal change as the coil was coming to expiry date. Now I've had it replaced and I have no side effects. Stable mood, skin clear, no periods, no stomach/back/head pain.

In terms of contraception practically perfect, I react extremely badly to hormonal contraception usually and this didn’t cause any of the negative side effects I usually get from hormonal methods. My periods became lighter and I still have the normal symptoms of my cycle which is exactly what I want. The only negatives (which is quite a big one) is significantly increased pain throughout my cycle, during my bleed and also cramping randomly throughout the month, sometimes when exercising and also two days before my period which I didn’t experience before. I am devastated that this has been discontinued in most places. I think it’s completely inexcusable that there is now no IUS which for most people doesn’t stop their period. One other slight negative at the beginning was my partner took some time to get used to the feeling of the strings when having sex, however this improved after a few months and is no longer an issue.
