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've not had any significant side effects...so far. But the one thing I don't like is that I struggle to track my period. I don't bleed it bleed very little. Some periods are just spotting. In theory this is great, but the rest of my body is still experiencing a cycle and without the bleeding it can be hard to track. I still try to, but I'm about ready to give up. If you are like me and spent 10 years on the pill, this can feel a bit jarring. I'm on a hormonal rollercoaster that is normal but I'm not really use to it. My cramping is normal compared to before I had coil. I've had acne rosacea crop up and after a year of it I strongly thing it's linked to hormones but not sure how much the coil plays a part (though I did NOT have this before coil, I am also 40 and may be perimenopauseal). Insertion recovery was totally fine. Very little discomfort. However I was undergoing a minor gyno procedure at the same time and as a result got a general! Highly recommend should it be available. Won't lie, not sure I would have the coil again after this one....I'm still not sold in all honesty. It just emotionally felt evasive as a method of BC.

Overall my periods were regular but once I got the coil I had very irregular periods and extra cramping. I also have frequent dizzy spells and headaches since it has been inserted. And I've seen an increase in spots and body hair since starting with the coil

Struggled to fit the Mirena & so fitted the Kyleena instead - potentially leading to an insufficient amount of progesterone as i continued to have irregular bleeding. After about 12 months this settled down and month on month this has lessened and my cycle continued. However, I experienced consistent cramping like I'd never had before and from 15 months onwards severe & debilitating pain about a week before my period. This is why I had it removed.

I experienced irregular periods, major mood swings and no sex drive at all. Would not recommend this at all.

Insertion isn't pleasant, but once it's in place, there's nothing to do for years! I had my first Mirena coil over 8 years ago and haven't had a period since insertion, only very occasional spotting (maybe once every 3-6months). I know some women like to track their cycle, but I never think about it and prefer it that way! Would recommend.

The threads disappeared on the first coil so had it changed early (wasn't great as they had to go digging about to find the threads). Had another put straight in at the time thinking it was a one off but the same happened with the second so I had it removed early as soon as I noticed them becoming shorter to avoid the first scenario again and switched to the implant. Great that my periods stopped on it and it's super low maintenance though.

Extremely painful insertion. Blood loss continuously for about 3 months, bleeding everyday. Then periods became irregular, passing clots the size of my palm. Periods worsened after merina, when ironically merina was prescribed for heavy periods. Dermatitis caused by merina after 2 months. Told that results with merina are variable, and to wait and see. Not good advice considering the health issues and extreme blood loss caused by merina so far.

I mean as a contraceptive it works because I haven’t gotten pregnant. A positive my periods are extremely light and irregular, but as a distant irregular. But my skin has never been so worse in my life, I constantly have big deep spots on my chin. I used to have quite dry skin but now on the oily side.

The mirena coil stopped my periods and worked as a contraceptive, however it stimulated hair growth on my face which was not there before. As a result I have required many courses of laser. I do not have PCOS and have had testing, however I think the hormones in the mirena coil started the changes that are now continuing despite having the coil since removed. The coil was also extremely painful to have inserted.
