Periods became heavy which was expected but cramping after insertion was incredibly painful and I was not prepared for the level for pain. I required A&E support with pain relief and examination to ensure it hadn't moved or perforated. The monthly pain had me missing work, almost fainting and squirming in pain. I had to learn pain management every month to be able to work effectively. Around 1 year later I felt in control but around 3.5 years I have experienced even heavier periods and more pain. I felt determined to make this method work as I didn't want to use hormonal contraception again. Cramping and heavy bleeding caused nausea, extreme fatigue and ovulation cramps. Overall, I experienced a lot of discomfort and only a few days out of the month where I felt well. I recently got told my iron stores are VERY low and that explains a lot of the worsening menstruation symptoms due to losing too much blood per month from the copper coil. I'm not going to scored it as terrible as I know others have had no issues using the copper coil and there were times when I felt in control of it. Maybe my age and change in hormones have made my symptoms worse? Or it just sucks, I don't know. Take ibuprofen and paracetamol before your insertion as this will help a lot!!

The insertion was painful and for the rest of the day I had severe cramps, which paracetamol and ibuprofen didn't help with. I wasn't given any option for pain relief at the time, if I had known it would have been so bad I would have asked whether pain relief was available. After insertion, I went from having manageable periods to very heavy and painful periods (severe cramping particularly on days 2/3 of my period). Naproxen was the only thing that helped to somewhat ease the pain. I persevered thinking it would get better with time, but after 11 months of no improvement I decided to have the copper coil removed. My partner and I also noticed that we would both get very dry and my partner would get cuts on the head of his penis, since removal these have not been an issue. It could be a complete coincidence, but when I asked the nurse removing my coil she said it could be possible... the cuts could have been a result from the dryness or could have been directly from the coil itself (depending on the position of the strings, and they were still quite firm as they take a while to soften). Everyone's body is different and for some this may be a great option (I initially thought it would be due to it being non-hormonal), but I definitely noticed a negative impact on my mental and physical health every month. Since having it removed (2 months ago), I feel a lot better and my periods have pretty much returned to normal.

I got pregnant because my copper coil moved down towards my cervix. Could still feel the strings as normal. For 4 months prior to that I'd been having symptoms of vaginitis (dry feeling during sex without actually being dry and stinging during urination). The doctors told me it couldn't be the coil causing it but I now believe it was, instead they treated me for uti and yeast infection and dermatitis (none of which I actually had). So yeah I suffered pain for 4 months and then got pregnant. I wouldn't recommend because it's so hard to tell it moved, if you get symptoms of vaginitis or vaginal irritation ask for an ultrasound. Getting pregnant at 20 and then having to terminate the pregnancy is traumatic.

I loved the copper coil however it caused very heavy and long periods and I had to get it out after 5 months due to anaemia. I also have pmdd so I wanted to try something hormonal to ease this

Before having the copper coil, I’d tried all other forms of contraceptives. I got to a point where I felt, even though the copper coil would cause more heavier and painful periods, it was non hormonal so thought it was my old option (hormones really don’t suit me) The insertion was pretty bad I won’t lie but when it’s done it’s done! I never could feel my threads and my periods went from 5 days to 10 days. I went from being someone with light periods to unbelievably heavy; to the point I was wearing period knickers with two overlapped night pads for two of the days. The nurses said after 6 months my body would adjust and the bleeding would settle down. They started me on TXA as my ferretin and iron became low. To cut a long story short the bleeding never settled and I was still having ten day long periods. It was a horrible 12 months as I felt the majority of the time I was on a period and doing daily tasks or working proved very very hard some days. I became anaemic and would spend a lot of money on supplements alongside the prescribed iron. The anaemic led to a lower moon, zero sex drive, ravinous appetite and tiredness. I know they say research shows a small percentage gain weight on it and I was one of them. But they always like to say it’s others things like lifestyle. For me I was certain it was the coil due to the anaemia it causes. I’m 155cm and weigh 8 stone 3. I’ve always been that weight and I go to the gym 3-5 days a week, probably twice a week since the coil. I gained a stone in that year.

Brain fog ,Acne , weight gain , tender and painful breasts all the time as a result , extremely heavy periods, although it's non hormonal doesn't mean no side effects , be careful when considering " non hormonal contraception"

Very frustrated with the copper coil, if it didn't make my periods so heavy and painful I would continue as there has been no other issues you would likely see in a hormonal contraceptive. If you can manage 2 weeks every month in a lot of pain, then it's worth it for the other two when I'm fine and no mood changes

I got the Kyleena coil fitted in Jan 2025 - just for reference I am a 5"3 23yr old without ever given birth - the insertion was very uncomfortable but not the worst ever, I did it with my sexual health clinic as I find they are more patient and kind rather than a quick GP / hosp appointment. My 11 months with the coil were overall great, except extreme contraction like pain and very occasional periods that would either last hours or a day. I didn't bleed every month but would get the odd few days of a period, quite unpredictable. I got a scan in July time just to make sure it was in the right place due to the amount of pain I was getting, and was all fine. In November 2025 I suddenly got excruciating pain and was told the coil has moved (perhaps explains the contraction pain throughout the year, I presume my body was rejecting it). Thankfully I pushed for another scan otherwise I would've kept having unprotected sex lol. Despite all the above, I am getting another one fitted because it is a trusty bit of contraception - just be aware if you experience a lot of pain in the lower tummy, to get it checked out!!
