Like many others, I found myself unable to decide between a coil (painful) and hormones (just dont want hormones). Gynefix has been the perfect in-between solution for me. Hormone-free, but also not painful. Insertion was a bit uncomfortable. The gyno needs to pierce your uterus wall. It felt a bit like getting a tiny push somewhere deep inside which, rather than super painful, was just a weird feeling which is what makes it uncomfortable. During the week after I could still feel that spot but again it wasn't really painful just weird to be aware of an internal organ like that. Other than having to avoid strenuous exercise for a few weeks, the recovery was very smooth and I had no issues. You cannot feel the gynefix inside you which is amazing. I have noticed no difference in my periods other than that 2 weeks before my period is due, I get some light spotting. I was afraid that during sex, the guy would feel the removal thread, but this was not the case. The thread also curls around the cervix a bit (over time) which makes it even less noticeable. Maintenance wise it's also great. Just visit the gyno every couple of months to get an ultrasound and make sure the Gynefix is still in place. You get 5 years of protection. I wish the gynefix was advertised to more people because I believe it is an awesome solution for anyone that is looking for a pain-free, hormone-free, hassle free contraceptive.

I got my gynefix mini online and had it inserted at the John Hunter clinic in London. I had paraguard before which gave me terrible cramps and incredibly heavy periods: I had Jaydess for 3 years which gave low but manageable mood but I started having terrible back pains either it. Once I had it removed, back pains stopped. I didn’t use anything for a while and then tried the implant, which was awful! It gave me terrible mood swings and anger! Went back to jaydess and back pains returned and low mood. I started looking for other options and found gynefix and I am so glad I did! Insertion was painful and my periods are significantly heavier but nothing I can’t live with. No back-pains, no horrible craps and no mood effects! Thank you whoever created this! I really forget it is there and only sometimes can slightly feel it, but this is by far the best contraception I’ve tried! It was hard to find a dr to get it fitted and I had to order it myself as NHS don’t supply it, but worth it!

Got one at mortimer market in 2023 and other than a slight increase in discharge (normal discharge), which to be honest I don't think is related to the gynefix, I have had an amazing experience with the gynefix, I just wish it lasted longer than 5 years! Insertion was very smooth; uncomfortable/painful for sure but nothing terrible and not the worst pain of my life, I was able to walk home after the procedure. Had spotting / light bleeding throughout my cycle for maybe a month or two, and I remember having spotting for a few months, but honestly nothing crazy or super annoying. My period was a bit heavier for a few months after insertion but now it is back to my normal (I had light, minimal pain periods before the gynefix for context!). I love it and wish it was more available in the UK, fear that when I need it out I wont be able to get it on the NHS and I can't see myself wanting any other contraception.

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)
