At first stopped my periods for 1 year but after periods came back much lighter but at random times. Now periods are more regular and still light rather than random spotting. Recently the doctor found a cyst in my ovary they think was caused by the implant.

I really didn’t like this. I felt I was always bleeding and the first 3 months are brutal emotionally.

To me, the implant feels like a very fair tradeoff, where inconsistent spotting and occasional sore boobs is a price I am willing to pay to ensure I have the best protection from pregnancy. That is why I have rated it 5 stars, despite mild side effects. I have had the implant for six months now, and I can honestly say that it has been immense. My copper IUD gave me heavy periods and back pain which would ruin my day, and caused me lots of stress when it randomly decided to dislodge itself after 3 months. The implant cannot dislodge, so this was a welcome improvement. My partner and I used condoms but were worried about the risk of "human error". I was hesitant to start hormonal birth control because I heard stories about people losing their libido or experiencing emotional/personality changes, but these changes have thankfully not occured for me! I may cry slightly more (at films and such) since getting the implant, but I don't actually feel any sadder if that makes sense. Prior to contraception I always had easy, regular periods. Since getting the implant, I have only experienced two physical side effects. One of these is irregular spotting for ~7 days at a time, once or twice a month. This spotting sometimes becomes period-like in terms of the bleeding, and occasionally comes with period-like cramps. I have found this to be easily manageable, but some people find it very frustrating and everyone will have a different experience. It's up to you which side effects you are and aren't willing to put up with. The second side effect for me is sore boobs, although I haven't experienced this for a while. I am hoping that this side effect has run its course now that I have had the implant for 6 months. In terms of the insertion process, it was a ridiculously easy procedure (although I only have an IUD insertion to compare it to). If you're scared of needles I would recommend taking a friend with you because they inject your arm to numb it (mild pain for under 10 seconds, then it's numb). As someone who isn't bothered by needles and had such a friendly doctor, getting the implant was nothing more than an excuse to be taken out for a celebratory dinner. Please don't let the insertion process put you off! Whilst the insertion may sound more inconvenient than picking up a box of condoms or a prescription, it is very straightforward and will only require a 10-minute doctors oppointment every 3 years. I had the implant in my dominant arm and I was able to do normal everyday things, although I had to be cautious about lifting things or raising my arm for the first few days. The bruise took about a month to fully fade, but the mild-moderate aching was gone within a week and a half. In summary, it is so easy to read these reviews and make asssumptions about the implant based on peoples stories of irregular bleeding, painful insertions and hormonal side effects. BUT it is not a negative experience for everyone, and I am so glad to have the implant!

I liked that it was minimal effort once inserted. My periods were far lighter and less frequently occurring. Because of the thickening of vaginal fluids being part of the mechanism; I found I because much more prone to UTIs after sex and also had lower sexual drive. I came off the Mirena because I wanted to track my cycle accurately to see if my hormones and cycle were affecting/triggering my seizures (I have drug resistant epilepsy). When I came off the Mirena I found I was less anxious over the months following swapping to the copper coil I.e. non hormonal. This had not been a concern of mine when on it.

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)
