My experience with the copper IUD happened over an 8 year period. Had my first copper IUD for 5 years, ages 19-24, was perfect, periods were heavier for around 3 months but went back to normal. No pregnancies, no pain, literally was a miracle contraception for me. Lost my IUD card so was not sure if I had a 5 or 10 year coil, clinic is impossible to get in touch with, so I thought I would get it replaced just in case. After replacing it I had horrible cramping, periods so heavy I would see stars, pain not only after sex, but after masturbating no longer than 2 mins. 6 months into my second IUD I went for scans and check ups as the pain was not getting better, everything seemed to be in place. Went to the clinic for a consultation and they advised get rid of it or go for the Kyleena. Got the Kyleena IUD which was amazing until I fell pregnant after having it for a mere 11 months. Terminated the pregnancy and went back to the copper IUD. I had three copper IUDs (YES 3 separate insertions) due to two of them moving out of place. All 3 of them gave me insane amounts of pain, WAY worse than the 2nd IUD, I’d get cramps going to pass a bowel movement or even overeating. Got this last one scanned and checked out due to the pain that was not subsiding, everything was in place, decided to leave it in despite the pain for another 3 months as I just really wanted it to be like the first one. After 3 months I was so depressed from how much pain I was in, I got it removed and now I am pain free. Giving this three stars because my first IUD was the best and I wish I could go back to it, the other 4 were seriously having an impact on my life and mental wellbeing, I spent a whole session with my therapist talking about my traumatic experience with this bloody thing. Please note I am an anomaly, but if you have it and the pain is not subsiding, do not hesitate to get it removed, some people’s bodies (such as mine) just reject it for whatever reason.

I really had high hopes that the copper coil would work for me, as in theory it sounds great! However, after a long wait and several appointments later. I finally got the copper coil inserted. However… two weeks later, the coil had to be removed, as it had moved down from my uterus into my cervical canal. Which can happen and is apparently rare! I was just unlucky. Due to me never being pregnant or giving birth (according to the GP) insertion procedure without anaesthetic was super difficult and quite uncomfortable for me. Luckily the GP didn’t push and force her way through my cervix and stopped the procedure after struggling for a while. The GP then referred me to my local sexual health clinic, to have the procedure done there instead. As apparently they have more facilities available and can apply anaesthetic to your cervix, in these types of situations. When I finally had the procedure done, it was a positive experience, thanks to the anaesthetic!!! It did hurt a little. The pain felt like a sharp period cramp that came and went! I wouldn’t recommend the coil personally, as in my experience it was a faff to get done and then only to have it removed two weeks later! Also, with how easily the coil moved! And the procedure being slightly painful, even with anaesthetic. All of the above is not ideal!

While I had my Levosert, I liked it. I had mood changes, and cried a lot more than usual, but mostly just leading up to my period so it was manageable. I had recurrent thrush with it, and actually ended up having a prescription for monthly fluconazole tablets. In the end, after around 2 years, my coil slipped into my cervix, and it was incredibly stressful. I had no symptoms that it had slipped down, except my strings were a bit longer than usual. A doctor mistakenly told me it was fine to keep using, but when I later had it checked at a different clinic with ultrasound, they were alarmed that I'd had no symptoms as it was pretty much almost out of my body. I'd essentially been unprotected for about 8 months, and this led to a big pregnancy scare.

The mirena coil did effectively reduce menstrual bleeding and prevent pregnancy. Due to thickening vaginal discharge I found I was more prone to thrush and also that this had an impact on arousal. I was an advocate for the hormonal coil until I changed to a non hormonal birth control and found that this had elevated my anxiety certain times in my cycle. I am epileptic without seizure control and this was my reason for coming off hormonal methods. Female hormones can trigger seizures in women with refractory epilepsy!

I was on the Kyleena IUD for 10 months after being on mirena for 5 years. Kyleena has had a terrible impact on my mental health and the reason I got it removed was because increased hair loss.

Have only had the coil for 2 months (although feels like much longer) so will give it a bit more of a chance, I also acknowledge that everyone reacts differently and my side effects seem to be less common, however in my experience and at this point in time, the negative side effects FAR outweigh the positives. My GP talked me into trying Mirena for managing my PCOS and the excruciating pain I would experience on occasion from burst ovarian cysts, as well as the birth control aspect. I’ve gone from an abnormally long (but fairly painless) cycle to an even longer one, bleeding and in moderate-severe pain almost daily. If my stomach doesn’t hurt, my head will be, or both. I’m not joking when I say I look pregnant from abdominal swelling on top of it all.

It was a very positive as i was having irregular heavy periods And personally I had a much better libido When in the past, bloods tested low in testerol levels of 7.5 i II wish this had been aware of of this before bow, i thought there was something not quite right as apparently 12 or above is the better level of testerol for women

I've had the Mirena coil for about 10 months now, my doctor recommended it to stop uterine polyps from reappearing. Prior to the coil I had very heavy, extremely painful periods and pretty bad iron deficiency, but now my periods are super light and not painful at all!! The insertion was painful but not worse that the period cramps I used to get before; I spotted for 3 months straight but after that I started having semi-regular periods. I noticed that I had much more energy (probably because my iron levels were back to normal), my libido increased and I lost weight. I am really really happy with the coil.

Awful experience having it fitted, very painful. I’m convinced it triggered vaginal atrophy (I was already menopausal)

I swapped to the coil as I started getting migraines on the combined pill and wanted a longer term solution GP advised to give the coil 6 months to settle in but during that time my skin has gradually got worse with bad acne, I still have periods which are lighter granted but lasting 8-9 days, much worse periods cramps than on combined and then for last 2 months spotting almost everyday and bad period like cramping. GP thought these symptoms suggested coil displacement but USS confirmed it was in situ and these must just be the side effects I personally get from mirena. The cramping and constant spotting and acne is affecting my sex life and general mood day to day so trying to get the coil removed and tempted to try the copper coil (although I went for the Mirena as I’d read you can get the symptoms I’m currently having on the copper but only time will tell!)
