Implant vs Copper coil (IUD)

I am so far very happy with the nexplanon implant. I had tried iuds prior, first the copper T, which did not work for me at all, and then mirena, which was good, but I did experience some pelvic pain and discomfort during intimacy. With the nexplanon, my periods stopped for the first year and a half, maybe closer to 2 years. And then was just very light spotting for awhile after that. I am at about 2 years and 6 months, and my period has come back fully, and I am starting to have hormonal acne and mood changes, so I opted to have it replaced, just in case these symptoms are due to the hormones tapering off. I just had it replaced today, so I am not sure whether it will fix the issue, but will keep ypu posted.

It cause me to have my period for 145 days straight starting two weeks after getting it. The first month was honestly horrible with severe cramping and lower back pain while passing relatively big clots. It also made my mental health decline significantly during this time but after the five month mark I am feeling great and not pregnant!

I was on it for coming up to 8 years overall obviously great to not get pregnant and I was on contraception before where I had an accident so it was really easy and really quick to not have to think about this. It did really impact my moods and I eventually ended up having PMDD because of the severe mood swings. I would also bleed twice a month instead of just a once And it caused a really bad loss of libido and federal dryness. But these are all things that would probably happen if I was pregnant anyway.

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 pregnant

The only down fall is low iron this has caused debilitating fatigue, so be prepare to have to maybe take iron supplements

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!!

I may have only had mine for 6 weeks but am currently very happy with my decision. Decided to get it to prevent a potential pregnancy as the morning after pill was potentially not going to be effective for where I was in my cycle. The insertion was uncomfortable as expected but the nurses were phenomenal, i was given a lidocaine gel and they talked me through every step. Had 24hrs of quite hefty cramps and light bleeding post insertion and it triggered my period early a few days later which was longer and heavier than my usual, but since then things have got back to normal in terms of my cycle length and symptoms I usually experience throughout and my next period came on time. Yes it’s heavier, a bit longer and the cramps are sometimes tough, but with a good regimen of painkillers, hot water bottles and being kinder to myself, i would take that over the risk of pregnancy any day. My partner doesn’t feel the strings when we have sex either. Will update in a few months 😊

Changed from mini-pill after 16 years as I wanted to know my body without hormones and start to understand my cycle better. No issues with the copper IUD. My periods are a bit heavier but they are more predictable and regular. I do have more cramps but they are manageable. Insertion was fine, just uncomfortable. I was surprised how quickly the cramping started after though. I was in quite a bit of pain for an about a week as it settled in.

I genuinely love my copper coil (IUD) that lasts 10 years, and I wanted to write this review as I used to hear horror stories about it and it almost put me off, but I didn't experience this and I want to reassure others that may be considering this. I got my copper coil in March 2023 after an unwanted pregnancy as a last resort. No hormonal contraception worked for me and I often experienced negative side effects, so I felt my last attempt was the copper coil. What a GREAT choice! Yes, the insertion is uncomfortable, but I asked for cervical numbing cream and it was mildly uncomfortable for two minutes. Definitely bearable with numbing cream. Since then, my periods are still regular a little bit heavier. and I do get a few more cramps. Very easily managed with a menstrual cup and painkillers. I love not having to think about my contraception, and I don't need to think about getting it replaced for TEN years. What a dream! It's a life saver for those of us that struggle with hormonal contraceptives.
