This post is for those considering the copper IUD. I know it is scary and you can find many horror stories online, so I thought I make the effort and share my IUD journey with you which has been very positive. Insertion: Got the IUD on the 4th February Insertion was uncomfortable and for a few seconds very painful but it did go away very quickly. I did bleed a little bit as well but I always do when they are examining my cervix. I’m very sensitive down there. Note:I have never given birth and my GP said that it can be more painful for those who never given birth vaginally. The GP who did the insertion was absolutely brilliant. She talked me through what she was doing and she prepared me for the most painful part. There was also a nurse present who was literally holding my hand through the whole procedure. It was such a positive experience. I’m grateful for both of them for making this experience so manageable. Right after insertion: I wasn’t in pain afterwards - I only had a mild sense of discomfort like you would have after a smear test. I even went for an hour walk right after the procedure, so it was really not bad at all. Please note that I’m a physically active person, so walking for an hour doesn’t tax me much. Others might have different experiences and it’s absolutely fine if you just go home and rest in bad for the rest of the day. That’s what i was told to do to be fair. Days After insertion: The cramping was moderately bad after the next 4-5 days, spotting was light After the 4-5 days cramping intensified especially after exercise and at some point the pain made it difficult to walk. Never felt cramping like that before. It made me very irritated as well. Normal painkillers didn’t work, I had to take cocodamol to get some relief but it was short term. Later it turned out that it coincided with my PMS. I was bleeding everyday after insertion, so it was hard to determine what was menstrual bleeding or bleeding because of the IUD insertion. Around day 11 cramping settled significantly. I only had occasional cramps which don’t require pain killers. I think I got my period on day 12 (16th Feb or 15th Feb) because the bleeding intensified around that time. It is the 17th February today. Moderate bleeding (more than usual but moderate) very light cramping. Fast forward March. After my period in February, I did not experience anymore unusual cramping - even after exercise. I got my period on the 9th of March. I did have some light cramping and mood changes as PMS but nothing unusual. The cramping was very moderate and did not require painkillers. Bleeding lasted 6 days with 3 days of heavier bleeding -3 pads a day- which for me is heavy bleeding. I have had sex a few times since insertion and my partner couldn’t feel the strings, so no problem there. Did not experience any dryness and my sex drive during ovulation is definitely higher than when I was on the pill. Overall very happy with my wee copper coil. 😊 Just a reminder that negative stories often get more attention than they deserve—people are more likely to vent about bad experiences than take the time to share positive ones Will keep you updated!

I’m writing this purely because of how terrified I was going to get the coil after all the horror stories I read about on here. If you are prepared the insertion is an absolute walk in the park. I took 2 feminax and 2 paracetamol about 45 minutes before my appointment, chose the local anaesthetic (call in advance to check you can get this!) - I literally hardly felt the anaesthetic at all and then the insertion is like sudden onset of moderate period pain but again it was nothing as bad as I was expecting!! The 24 hours after I kept using the pain relief tablets and I haven’t needed to use it since. A tiny bit of bleeding since which I think will continue for a few days but that’s it. If this fear of the insertion is what’s stopping you from getting either coil please read this! I almost didn’t get it because of the anxiety I had around fainting / extreme pain etc. that I read about. Eat before, take pain relief and get the local anaesthetic and you will be so fine

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!

I have possible adenomyosis and this coil was only temporary as emergency contraception to then get switched to the mirena but my second period has been lighter and much less painful than before so I'm considering waiting to see how this goes. I don't get hormonal migraines either

Amazing option for non-hormonal contraception. Yes it does hurt a lot to insert & my period is heavier but i think it outweighs any mental/physical changes other options have. My biggest & only issue is thrush! I get it every single month and no one warned me. Looking to get this sorted because it’s become a challenge and so frustrating.

I wanted to get a contraception that was hormone free as I’d been on the implant since I was 18 and by the end of it my mental health had definitely taken a toll (my anxiety was unpredictable and awful!), as well as experiencing regular spotting. I went for the copper coil and the experience was pretty straight forward - I didn’t take painkillers beforehand because it was 9am (would not recommend getting the coil fitted at this time haha) but the lady gave me a numbing cream of some sort without me even asking which I appreciated. The pain was pretty bad but in an achey way - when she inserted it I could feel my uterus cramp up. I could barely walk home because it felt like the worst period cramp in the world and I got home and took some painkillers and cried it out for a few hours. I wouldn’t say this deterred me though and honestly I would recommend what the GP told me which is a mix of ibuprofen and paracetamol the day you’re getting it inserted. After this day, it was fine and an amazing decision. My hormones go up and down when they’re supposed to and I follow my cycle pretty accurately which is fun for a change! My periods are heavy on one day out of four or five that I’m bleeding, but nothing I can’t handle!

As I was reading these reviews before getting mine inserted I thought I’d give back by sharing my own experience also. I am writing this while very fresh in mind and I have only had it for a few days, so I cannot comment on long term effect yet. As I was mentally preparing to have it inserted, I was quite scared due to the many comments on how painful it would be to have inserted. What was not clear to me was the difference in terms of whether you have previously given birth or not. I could truely barely feel it at all and had no pain relief. I have given birth 2 times, and as late as 9 weeks ago. Wanted to share this as my physician also informed me that (here, Denmark) we only give pain relief to those who have not yet given birth. Other than that I experienced a little bit of slight bleeding for 1,5 days. Another thing worth commenting on is that you can feel the copper strings after insertion, so you can self-check that it is sitting right and in place. Hope my experiences also gives some comfort to someone else 😊

I had my copper coil for the full 10 years. I had always had slightly heavier periods before my coil however after having it fitted I suffered for years with extremely heavy periods that were painful and I would leak every time. They say it doesn’t make you gain weight however I gained 5 stone whilst on it. It came time to remove it and I was going to just have another fitted however the doctor couldn’t get it out i was bleeding everywhere and in intense pain. Was sent for emergency antibiotics for PID went through a week of feeling awful on strong antibiotics just for all tests to come back negative. Spoke to dr she thinks the coil was causing these issues. Had it removed eventually (thank god!) decided against having another one! When the dr took it out, my coil that was supposed to still have a few weeks left had 0 copper left of the coil! So was completely ineffective at this point! Terrible experience!

From very heavy periods to light and now basically non-existent this has been a real blessing. Didn't suffer much from mood changes prior and hasn't affected me there either. Cramping on and off occurred for around the first month. Feel a lot freer

After many years if suffering from side effects from hormonal contraception, I have decided to swotch to copper IUD and couldn’t be happier. The insertion was unpleasant but not painful. My period is a bit heavier and cramps a bit stronger but nothing dramatic and I never have to think about contraception. I am really happy with it and can only recommend getting a copper IUD.
