Kyleena coil  

Kyleena was recommended with mr having Adenomyosis due to wrongly being given the copper coil before and bleeding for months on end. Kyleena had irregular periods to begin, the only sidr effect for the first 4 months were severe coldnesd/flu like symptoms the day before my period for all 4 months. As my periods stopped, my sex drive and mental health crashed. I'm on month 9 and awaiting removal.

Kyleena coil  

Having used the pill on and off for 20 years I was hesitant to use another hormonal contraception but I was so happy with kyleena - no noticeable mentsl or physical symptoms. Insertion is not pleasant but it's over in seconds.i experienced some period cramps in first few weeks but then periods became extremely light and pain free for the last 3-4 years. I would get this method again without hesitation.

Mirena coil  

I had a terrible experience with Mirena. It started with severe cramping after insertion. The cramping continued for weeks. I got a UTI from it. Then the other symptoms started - severe depression, sneezing, severe sinus pain, insomnia. I experienced severe vaginal dryness and vulvodynia (shooting pain down there) which ultimately led me to showing up at my gp and begging for it to be removed.

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.

Nexplanon implant  

Really easy insertion process, nothing to be worried about as a local anesthetic is used. Luckily so far I haven't had a single bleed on this (touch wood) although I had this fitted 2 months postpartum and my periods hadn't properly come back yet. I kept forgetting to take my pill and so I love the implant so far as it's automated contraception that requires no effort for 3 years! Perfect for a busy mama!!!

At first stopped my periods for 1 year but after periods came back much lighter but at random times. Now periods are more regular and still light rather than random spotting. Recently the doctor found a cyst in my ovary they think was caused by the implant.

I really didn’t like this. I felt I was always bleeding and the first 3 months are brutal emotionally.

Nexplanon implant  

To me, the implant feels like a very fair tradeoff, where inconsistent spotting and occasional sore boobs is a price I am willing to pay to ensure I have the best protection from pregnancy. That is why I have rated it 5 stars, despite mild side effects. I have had the implant for six months now, and I can honestly say that it has been immense. My copper IUD gave me heavy periods and back pain which would ruin my day, and caused me lots of stress when it randomly decided to dislodge itself after 3 months. The implant cannot dislodge, so this was a welcome improvement. My partner and I used condoms but were worried about the risk of "human error". I was hesitant to start hormonal birth control because I heard stories about people losing their libido or experiencing emotional/personality changes, but these changes have thankfully not occured for me! I may cry slightly more (at films and such) since getting the implant, but I don't actually feel any sadder if that makes sense. Prior to contraception I always had easy, regular periods. Since getting the implant, I have only experienced two physical side effects. One of these is irregular spotting for ~7 days at a time, once or twice a month. This spotting sometimes becomes period-like in terms of the bleeding, and occasionally comes with period-like cramps. I have found this to be easily manageable, but some people find it very frustrating and everyone will have a different experience. It's up to you which side effects you are and aren't willing to put up with. The second side effect for me is sore boobs, although I haven't experienced this for a while. I am hoping that this side effect has run its course now that I have had the implant for 6 months. In terms of the insertion process, it was a ridiculously easy procedure (although I only have an IUD insertion to compare it to). If you're scared of needles I would recommend taking a friend with you because they inject your arm to numb it (mild pain for under 10 seconds, then it's numb). As someone who isn't bothered by needles and had such a friendly doctor, getting the implant was nothing more than an excuse to be taken out for a celebratory dinner. Please don't let the insertion process put you off! Whilst the insertion may sound more inconvenient than picking up a box of condoms or a prescription, it is very straightforward and will only require a 10-minute doctors oppointment every 3 years. I had the implant in my dominant arm and I was able to do normal everyday things, although I had to be cautious about lifting things or raising my arm for the first few days. The bruise took about a month to fully fade, but the mild-moderate aching was gone within a week and a half. In summary, it is so easy to read these reviews and make asssumptions about the implant based on peoples stories of irregular bleeding, painful insertions and hormonal side effects. BUT it is not a negative experience for everyone, and I am so glad to have the implant!

All the great wetness I was feeling down there is all gone. I have painful sexual intercourse and I'm sad.

Poor experience. Great at preventing pregnancy however side effects on mental and physical health were not worth it. I chose to prioritise my health and swap to condoms.
