Copper coil (IUD) vs Hormonal coil (IUS)

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 was having heavier periods

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!

Had the coil for just over a year and bled daily (although only light). Only had a few days a month not bleeding

Generally the Mirena has been great. Only noticed most of the side effects after 4 years having it in - and they’re still very manageable.

So I’ve had the kyleena put in just over 2 years ago. For the first 18 months it was great, there was no side effects and my periods were getting lighter and less painful! After that, I started noticing quite a bit of hair loss during showers and brushing, visibly making my hair look thinner. I’ve always had thick hair so this was quite upsetting and I put it down to the stress I had during college. Now I’m in a new job that I’m loving, the hair loss hasn’t subsided. It’s still falling a lot everyday so I’m deciding to get the kyleena removed in a months time. I’ve been to the GP and got bloods done in which everything came back fine. So hopefully once I’ve the kyleena removed my hair will slowly start growing back :(

Not 100% sure what to think yet. Enjoying not having to worry about administrating my contraception as it’s in there and working. However I am having unpredictable spotting, some emotional mood swings and often being bloated.

Overall this was a good option for me. The insertion was painful but momentary, and was nice not to have to worry about taking pills. The spotting occurred more at the end of the coil’s lifespan (I’m having it taken out this week after 5 years). I did notice vaginal dryness (most noticeable when aroused, needing lube etc). Ultimately I am coming off this contraception because of this. I have vaginismus and the dryness hinders my ability to get/feel aroused. I know this is because of the coil because I have felt the effects wear off as the coil gets to the end of its lifespan (in the last 6 months of my 5 year stint)

I had the worst time on Mirena. I had a bad experience from day one at insertion - I found the whole experience so much more painful than I imagined that it would be - no one really prepares you for this. From the first day I started experiencing cramps and everyone said that they would ease up within no time however they did not. Month after month I experienced endless painful cramps and times where I would be doubled over in two on dates with my boyfriend - never have I had anything like that. As a girl, we very much always shut up and put up and I always felt like I could just push through it but there were times when it was really bad and I almost got it out, but you’d forget about it the next day as it’s such a good feeling to not have to Take a pill etc and it is very convenient. But it’s also crazy I actually had it in for as long as I did. I have never really had that bad periods and my bleeding was longer, the cramping much more intense and honestly just a whole lot worse than it was when I was off it. I didn’t really notice anything kind of sexually or from a weight or ski. perspective but I know that the cramping and the bleeding was enough for me to never touch this thing again. The Doctors kept telling me to hold out and just wait to see if it would change and it just never did. I would really recommend if you are having these symptoms any time past two months they are not going to get better and you’ll just continue to suffer. At the eight month mark I went and got it out and honestly it was the best thing I ever did. As soon as it was out, I felt like I could actually breathe again and havent suffered another cramp like it ever since (thank god!). I have gone back onto the mini pill now which I’m much more happy with - it does have some side-effects but nothing like that cramping!

I had this inserted and I was the worst pain ive ever experienced i kept telling the doctor to stop immediately after I blacked out from the pain kept being sick and it just got worser as the day went on I end up in ane with the same day and had it emergency removed. Never again will I have this would not recommend at all .

I feel like myself, which I cannot say for other forms of BC I’ve used. The weight gain may have more to do with some lifestyle changes, but I enjoy the way my body look regardless. I was able to collaborate with my doctor to find suppositories to help with the dryness during sex and that in turn has helped with my libido. I cannot imagine using another form of birth control.

I had a Kyleena coil inserted, after 6 months I was still having week long breakthrough bleeds between periods. I had the coil checked and it was in position, no problems according to the doctor. A month later I was pregnant, with the coil still in the correct place. Unfortunately the Kyleena coil didn't work to protect me from pregnancy, caused me to have breakthrough bleeds and have recurrent episodes of thrush.
