First 6 months is an adjustment period so I had plenty of headache and feeling sick but after a while my body used to it and I am fine. 100% contraception effectiveness and no heavy period.

Insertion was definitely a little more than just "uncomfortable', it was incredibly painful and emotionally felt very invasive. Took about a day or two to get over the cramps. Felt very faint the first night after having it inserted. Have had experience with SA before though and after telling the nurses they were incredibly supportive throughout the procedure. Side effects wise I got on pretty well for the first year. My periods did stop after a few months, which I found to be a bit strange as I like to track my cycle and I found this a bit strange at first, as I could feel my other symptoms of my cycle but felt a bit off kilter when I didn't have my usual period. Not having to worry about condoms or taking a pill everyday is great though. But after about a year of having the hormonal coil I've noticed my mood and mental health take a bit of a dip. I feel a bit like my emotions are just sitting a bit flatter, I'm a bit more irritable, I don't experience quite the same amount of joy as I used to. I do have a lot going on in life at the moment, but I can't help but notice day to day, even on good days, that I'm not as cheerful or reacting to things in the same way I used to. Emotionally not feeling like myself I don't feel is worth this,no I'm going to seek advice on whether to have this removed or not I think.

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!

My experience of the copper IUD is mixed, even if overall positive. I first got it as emergency contraception after my first sexual experience, and was not properly offered any pain relief. The pain was excruciating and slightly traumatic, but also as I wasn't used to things going inside my vagina either. However it served me perfectly for 5 years, and no hormones and side effects from those. When it was time for renewal I was prepared emotionally and knew what pain relief to ask for. The procedure itself was quick and felt very empowering. They offered me the 10 year one which was slightly bigger and I thought it was no big deal. I was in constant low level pain and discomfort with it, and periods became excruciating. I got it switched back to a 5 year one and this cleared up. Again. the procedure was fairly quick as I knew my body and had good pain relief. My last one suited me fine up until around 2020, when the combination of the stress from the pandemic and using an expired lube gave me recurring yeast infections that lasted at least a year. I then discovered that it had slipped and so got it removed, deciding to switch to Fertility Awareness Method. After that, the recurring yeast infections stopped.

Personally, I would never get another coil again. The reason for 2 stars is I actually had the copper coil inserted in 2018 and it was okay but I had it removed in 2021 after asking for it to be removed for over a year. My periods were heavier as expected, but I also had thrush every month, BV multiple times and it just became so uncomfortable dealing with this constantly. I had the copper coil again this year (march 2025) and it was awful. The insertion this time took an hour compared to the 10 minutes last time. I was in so much pain I was heaving, I have had three babies and this was worse than birthing a child. They finally got it in and I ended up with a mild infection probably due to how long and how many attempts it took. A week later it started to settle down 🤞🏼 however almost three months later and I'm having it removed next week. I don't know if it's misplaced (they will be checking this first) but I feel it 'stabbing' me randomly every day. I will be walking and suddenly stop and feel like it's stabbing me or trying to come out, but I can still feel the strings. On two occasions it's hurts me during sex which is a red flag. My periods are 10-12 days long and I'm getting through a pack of pads every 1-2 days, plus the thrush is back again. I was offered a replacement however I have declined and I am currently trying to decide which combined pill may be best for me, tho I am nervous about going on the pill now!

I used to have fairly light and painless periods and I’m now in agony every month and bleeding through my clothes. I have it time to see if it would settle but it’s been a year so I’ve booked to get it removed and can’t wait.

After having children the contraceptive pill didn’t seem to work, I tried various types and had breakthrough bleeding. I decided to try the copper coil. Insertion was so painful but my periods have been regular and through tracking apps I’ve got to understand my cycle and know what my hormones are doing which I quite like.

The copper coil hurt the first day of insertion but then immediately settled. My periods have become slightly heavier and cramps a bit more painful but still very manageable with just paracetamol and ibuprofen. I am lucky in that my periods only last 4-5 days anyway. My moods change with a normal cycle pattern, I get some acne during my luteal phase. I love having protection but not having the negative impacts on my MH like hormonal contraception had. Would recommend.

It's so hard finding contraception that doesn't have side effects and I wanted a hormone free form, so opted for copper IUD. Insertion is manageable, with painkillers beforehand. The first period was tough, I invested in a tens machine pad but the cramps were hard, but not worse than the worst period I've had. Second period non existent, literally three days and barely any blood, but third was heavy and lasted for 10 days. I stopped using the coil not because of any of this alone, but because I'm sure the inflammation in my body was making me uncharacteristically anxious. So hard to put my finger on, but since I got it removed it's been a weight off my shoulders. I'm now worrying that hormonal IUD will make me more anxious, and I haven't had it put in yet. It's overall not been too awful- I wouldn't not recomend it but I had it put in for emergency contraception so hoping there is a better solution out there without the anxiety side effects.

Really liked this. Tried hormonal methods and ended up having a negative experience with them so had a go at this one. Works great. Most problems stopped after 6 months, like heavier bleeds and back pain etc. Eventually got down back to normal but it takes time to adjust. Genuinely made my life so much better, sex is great and I don't need to worry about hormones or my menstural cycle.

Seriously heavy periods (wearing nightime pads and a tampon and still bleeding through my clothes in like an hour) and sometimes extruciating cramping. A lot of spotting between periods also which I've never experienced before. Nurse has told me that the coil should not affect my bleeding and I've gone straight from the mini pill to this so it may have been that the pill was improving my regular symptoms more than I realised.
