Copper coil (IUD)  

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!!

Copper coil (IUD)  

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 😊

Copper coil (IUD)  

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.

Was previously on the progesterone only pill but did not want to have to remember it daily. Have had no issues with Nexplanon and had it changed recently after having the first for three years.

Nexplanon implant  

I would recommend getting the implant. There has been little to no difference in my body while using it and it has been a positive experience. I did notice my periods have gone from Light and regular every month to continue being light but very irregular and can last anything from 4 days to 3 months at a time. I also had one other negative experience a few weeks into having the implant. (I do think it was just my body adjusting as I haven’t had anything the same since). Where I was continuously being sick for 2 days, There was no signs of me being ill or have eaten anything unusual. I do think the implant has made very little changes to my body. Obviously a 3 month period is annoying but it does end you just need to be patient. I’m coming up to 2 years on my implant so I do feel as though my input is helpful as some people aren’t patient enough to wait out the symptoms like a long period.

Apart for heavy long periods, I Became mean and short fused. My sex drive is zero. I am less excited and feeling empty. Had the implant for 8 months, the behaviour changes are not settling.I am generally miserable and its damaging my relationship.

Nexplanon implant  

Safest and easiest contraception in my opinion. However does come with lots of side effects as any medication does, it is manageable but irritating at times (headaches, irregular bleeding every month and lower back pain). I also get rashes at the implant site quite frequently and heard this is very common- gets itchy but normal apparently

Nexplanon implant  

Of all the contraceptives I tried I was most satisfied with the implant. I had mostly no side effects and it stopped my period completely after 1 year (had some spotting irregularly in the first year). It was a very effective method, with painless insertion and changes (had 3 implants in 7 years). I removed it because I wanted to give my body a break before potentially trying for a baby. The main side effect and reason I took off one star is the loss of libido and vaginal dryness. My libido was very low and when I did get into sex, the dryness made things painful. Overall the sensation and pleasure of sex took a hit, but it was manageable. Now that I am off the implant I notice a resurgence in libido and feel more connected to my body and sexual self.

Nexplanon implant  

I had the implant for 19 months and got it taken out today after being a little fed up of the side effects. For the first couple of months, I had my period as normal and pretty much no other symptoms except being a bit more emotional. Then over the next year or so i had completely stopped bleeding and had no issues. Then I started to get migraines maybe 2 a week for a couple weeks (I had 5 in the space of a month?) and they were so unbearable. And then I started bleeding again but it was so irregular. I could have a period twice in 2 weeks but not have one for like 6-8 weeks and then get spotting for a few days. It was so frustrating. That and having incredibly sore nipples and tender breasts that I couldn’t wear anything without it hurting. Ever since getting it inserted I have gained around 30kg which is very noticeable on someone who is barely 5ft tall. So because of that my self confidence has completely dropped. It felt like I was buying a bigger bra every 2 months. And none of my clothes that I had a year and a half ago fit me anymore. Overall the beginning was pretty great but about a year in I didn’t like it anymore.
