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 😊

Sayana Press injection  

Great if you’re looking to prevent pregnancy with less admin. Having the year’s supply ant home and not needing to see a doctor every few months was handy. Stopped my periods aside from some very minimal spotting and my skin was great - I barely had any spots over the years I was on it. I did feel like I was quite numb emotions wise. I didn’t experience mood swings but it was alarming that I often didn’t really feel anything! My libido was extremely low too.

It's a good injection for me, I have been using it for longest time since I was 16 years started to use it. Who recommended it? Clinic nurse.

Noristerat injection  

took some time before i ever come here mainly because i was scared , shy , & hated myself for what im about to talk about here❤️ trust me when i say it’s hard ( im even trying not to cry ) shap so i started my pregnancy prevention journey this year on April it’s been 6 months now & never missed even a single dose (big ups!!) Starting it was so fun & games bcs i would notice some changes & that for me was a game changer bcs I’ve always wanned to gain weight so badzzzz ( i lost weight before so starting this journey for me was a bounce back ) may started eating a lot!! , June my periods desappeared July i got some pimples , august i experienced painful headaches, September my mood swings would change here & there & all that came unoticed to me because that one thing I’ve always wanned does not happen im not gaining still , bro im so drained i feel like it’s so useless for me to inject i don’t know but yeah hey i just hope god pulls through im even thinking of leaving it

I have had no negative side effects with Sayana Press and my periods have stopped completely, of the four different contraceptives I've tried over the years, this one is my favourite.

Depo-Provera injection  

Depo-Provera was great for me and it stopped my periods completely. I liked not having to take a pill everyday and I didn't want to get another copper coil so this worked well for me. However after being on it for quite a while I got unlucky and ended up with an abscess at the injection site which eventually had to be operated on, however this could have happened with any kind of injection and was just bad luck. I have since switched to Sayana Press so that I can do my own injections at home and clean the injection site beforehand to prevent another abscess.

Depo-Provera injection  

Worst experience I’ve ever had. Since taking this I’ve felt constantly irritated, had complete lack of concentration and it’s completely wiped out my sex drive. I have now been bleeding for 2 months with no break. I have never regretted taking something so much it’s honestly made me miserable.
