I really had high hopes that the copper coil would work for me, as in theory it sounds great! However, after a long wait and several appointments later. I finally got the copper coil inserted. However… two weeks later, the coil had to be removed, as it had moved down from my uterus into my cervical canal. Which can happen and is apparently rare! I was just unlucky. Due to me never being pregnant or giving birth (according to the GP) insertion procedure without anaesthetic was super difficult and quite uncomfortable for me. Luckily the GP didn’t push and force her way through my cervix and stopped the procedure after struggling for a while. The GP then referred me to my local sexual health clinic, to have the procedure done there instead. As apparently they have more facilities available and can apply anaesthetic to your cervix, in these types of situations. When I finally had the procedure done, it was a positive experience, thanks to the anaesthetic!!! It did hurt a little. The pain felt like a sharp period cramp that came and went! I wouldn’t recommend the coil personally, as in my experience it was a faff to get done and then only to have it removed two weeks later! Also, with how easily the coil moved! And the procedure being slightly painful, even with anaesthetic. All of the above is not ideal!

Insertion was incredibly painful. Was like a really bad first day of period that I had to take off work sick and take lots of painkillers for. Lasted about 24 hours then settled. Unfortunately cramps continued as coil had not settled properly and one of the arms got stuck in uterus wall so I had to have it removed. due to pain of initial insertion I did not want another one back in. HOWEVER SINCE GIVING BIRTH I had another coil fitted at 10 weeks post partum and could not feel a thing! I have the progesterone coil now and have not experienced any negative side effects, other than light bleeding for about 2 weeks after insertion.

I have previously been on the implant, the combined pill and the mini pill for many years and having to come off each for different reasons. I decided to go with the copper coil as coming off hormonal birth control it had felt so good to have my natural cycle back, but I’m not yet ready to have kids. Insertion: I went for a ten year one. The woman was lovely and talked me through the whole thing. It was painful - I won’t sugarcoat that - but it lasted only a few seconds. I had cramping and some bleeding for the next few days (had to use pads not tampons), but nothing too bad. After: I was really happy with my decision and most of the time forgot it was even there. It hasn’t affected sex at all. I will be really honest that my first period (and to a lesser extent my second) were really painful - much worse than normal and they do last a day or so longer. However now I’m 3/4 months in and they’ve returned back to normal on pain levels (just slightly longer as mentioned). I am back to ovulating normally (as I wasn’t when I was on hormonal contraception) and am feeling really happy with my decision to get the copper coil! It was very much worth the initial pain and a few painful periods for me. I like that I can now decide to just take it out if/when I want to have kids.

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)

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!)

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.

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.

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.

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.

I've had a mirena coil for about 7 months now. Before getting it I had severely heavy periods. Most months I got a bad migraine. My iron was low. The GP didn't suggest anything to help with the heavy periods/monthly migraines/low iron. However when discussing contraception mirena coil was suggested. (I'm 40, have had 2 children). I was wary to mess with my hormones but the doctor said it could calm down my periods too. It was a long wait (almost 12 months). As soon as I got it I haven't had such heavy periods. Migraines haven't been an issue and my iron levels are back to normal. I haven't noticed any mood or weight changes. I've been happier and healthier because I haven't been dealing with the bad periods anymore. My periods are irregular, but very light. The only negative is a couple of times I've had stomach cramps, quite painful ones, they've gone away in under a day. There has been no follow up with a health professional. It would be nice if they did this to reassure everything is normal and ok.
