Gynefix  
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  

So far I love the mirena coil! Insertion was definitely painful (not just “uncomfortable”!), but the pain was very brief. I had cramps for a couple of days, and then light bleeding/spotting for about a month. However since then I’ve had no periods, and don’t even know it’s there. I get a few more spots now but that’s from rarely getting any when I was on the pill, it’s not a lot. My weight has stayed exactly the same. I was terrified of getting it fitted but am so glad I did, if it continues like this then I will take 30 seconds of pain for 8 years of not having to think about contraception, no periods and no side effects!

Generally the Mirena has been great. Only noticed most of the side effects after 4 years having it in - and they’re still very manageable.

Kyleena coil  

So I’ve had the kyleena put in just over 2 years ago. For the first 18 months it was great, there was no side effects and my periods were getting lighter and less painful! After that, I started noticing quite a bit of hair loss during showers and brushing, visibly making my hair look thinner. I’ve always had thick hair so this was quite upsetting and I put it down to the stress I had during college. Now I’m in a new job that I’m loving, the hair loss hasn’t subsided. It’s still falling a lot everyday so I’m deciding to get the kyleena removed in a months time. I’ve been to the GP and got bloods done in which everything came back fine. So hopefully once I’ve the kyleena removed my hair will slowly start growing back :(

Not 100% sure what to think yet. Enjoying not having to worry about administrating my contraception as it’s in there and working. However I am having unpredictable spotting, some emotional mood swings and often being bloated.

Kyleena coil  

Overall this was a good option for me. The insertion was painful but momentary, and was nice not to have to worry about taking pills. The spotting occurred more at the end of the coil’s lifespan (I’m having it taken out this week after 5 years). I did notice vaginal dryness (most noticeable when aroused, needing lube etc). Ultimately I am coming off this contraception because of this. I have vaginismus and the dryness hinders my ability to get/feel aroused. I know this is because of the coil because I have felt the effects wear off as the coil gets to the end of its lifespan (in the last 6 months of my 5 year stint)

Mirena coil  

I had the worst time on Mirena. I had a bad experience from day one at insertion - I found the whole experience so much more painful than I imagined that it would be - no one really prepares you for this. From the first day I started experiencing cramps and everyone said that they would ease up within no time however they did not. Month after month I experienced endless painful cramps and times where I would be doubled over in two on dates with my boyfriend - never have I had anything like that. As a girl, we very much always shut up and put up and I always felt like I could just push through it but there were times when it was really bad and I almost got it out, but you’d forget about it the next day as it’s such a good feeling to not have to Take a pill etc and it is very convenient. But it’s also crazy I actually had it in for as long as I did. I have never really had that bad periods and my bleeding was longer, the cramping much more intense and honestly just a whole lot worse than it was when I was off it. I didn’t really notice anything kind of sexually or from a weight or ski. perspective but I know that the cramping and the bleeding was enough for me to never touch this thing again. The Doctors kept telling me to hold out and just wait to see if it would change and it just never did. I would really recommend if you are having these symptoms any time past two months they are not going to get better and you’ll just continue to suffer. At the eight month mark I went and got it out and honestly it was the best thing I ever did. As soon as it was out, I felt like I could actually breathe again and havent suffered another cramp like it ever since (thank god!). I have gone back onto the mini pill now which I’m much more happy with - it does have some side-effects but nothing like that cramping!

Mirena coil  

I feel like myself, which I cannot say for other forms of BC I’ve used. The weight gain may have more to do with some lifestyle changes, but I enjoy the way my body look regardless. I was able to collaborate with my doctor to find suppositories to help with the dryness during sex and that in turn has helped with my libido. I cannot imagine using another form of birth control.

Kyleena coil  

I had a Kyleena coil inserted, after 6 months I was still having week long breakthrough bleeds between periods. I had the coil checked and it was in position, no problems according to the doctor. A month later I was pregnant, with the coil still in the correct place. Unfortunately the Kyleena coil didn't work to protect me from pregnancy, caused me to have breakthrough bleeds and have recurrent episodes of thrush.
