I previously had the copper coil for 4 years because I wasn't keen on using a hormonal contraception but I wish I'd changed to benelixa sooner. I opted for a numbing injection during the procedure and hardly felt anything, it was great. Afterwards there was some very mild cramping and unfortunately I did get mild thrush within the week, however since then it's been amazing. Hardly any pain during periods and they are sooo much lighter. I used to bloat all the time but now I never do. I also lost about 4lbs and have stayed at that weight ever since. I had thinning hair previously and now have lots of new baby hairs coming in all over my head which I'm delighted about. Sex drive has decreased ever so slightly but not enough to be a problem. No changes to my skin or any other negative side effects. Really can't recommend it more, I'm delighted with not being in agony every month and I have much more energy since I'm only losing about a quarter of blood compared to before.

I’ve had the kyleena iud for just over a year. Initially, I had more painful periods but that’s common for about 6 months as your body adjusts but this has since gone away. After about 6 months, I started to suffer with vaginal dryness. This was easily managed with lube during sex but after a year it really started to get bad. It was causing constant thrust (5 times in 3 months) which I had never been prone to before and the pain during sex can sometimes mean we have to stop or I’ll be okay for a bit but then after will be bleeding or have sort of friction burns. It’s coming out soon but it’s just a shame about the dryness as I loved it otherwise

My first year of the coil seemed to be okay. Took a while to get used to and on the grand scheme of things after about 3 months my period pretty much left.. but in the last year, I’ve been getting symptoms of anger, forgetfulness and generally feeling checked out. Going to speak to GP to find another option.

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.

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 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.

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.
