Used for 12 - 18 mo

🇬🇧 UK
  •  27th Apr 25

Gynefix  

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.

Gynefix  

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!

Gynefix  

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.

Mirena coil  

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.

Mirena coil  

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

Mirena coil  

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)

Mirena coil  

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!)

Mirena coil  

Had the Mirena coil for 4 years. Insertion wasn’t a fun experience but only cramped for a few days. A bit of spotting for first few months but reduced to nothing for the next 4 years. Very happy with it, only getting removed to get pregnant.

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  

Had Mirena fitted to manage endometriosis after a laparoscopy. The period cramps felt worse than when I was on the contraceptive pill before the surgery. Also struggled with depression and low energy. Acne was about the same as before I started the contraceptive pill.

Mirena coil  

I really like the Mirena Coil, especially as the combined pill was my previous contraception which negatively affected my mood. I had a lot of spotting for the first month and now have the very occasional spotting, but it's great not having a period anymore.
