Kyleena coil  

Had kyleena fitted on recommendation from my doctor due to severe painful heavy periods, I have adenomyosis and suspected endo. Insertion was uncomfortable but not excruciating, the cramp lasted a couple of seconds and I was fine. Bleeding started within hours and didn't stop for the duration of use, I was having excruciating pain every day to the point I couldn't walk, feel my legs and awful tail bone pain. I booked an appointment a month later and my doctor said I didn't look well and removed it without me even having to ask. I wish it had worked for me but it just didn't. The removal was fine and gave instant relief.

Kyleena coil  

Was on the injection for over 6 years and was advised to change due to adenomyosis diagnosis. Injection gifted me no periods for 6 years and I’ve still not had any sine changing to coil. Insertion was painful but 6/10 initially. Hot water bottle and pills helped. Cramping did occur infrequently for 2-3 weeks post insertion. Breasts have definitely enlarged and far more tender to touch, feel heavier and unfortunately don’t fit my bra’s anymore. 1st world problems. No issues during intimacy or post either. Other than the cramps, no complaints!

Kyleena coil  

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

Mirena coil  

After taking the pill for at least ten years I thought it was time to reconsider my options. Used the Lowdown to eventually choose the hormonal coil. Insertion was uncomfortable but nothing unbearable (for me, I know alot of people have had horrid experiences). My periods are very irregular (think maybe four a year and more spotting that bloody). My hormonal state throughout the month is more consistent, no major ups and downs than I used to get on the pill. I couldn't fault this as an option and also not having to remember to take the pill everyday was a huge bonus. Recent changes to the length of time for changing them meant I got an extra two years out of mine. Great long term option if you know you don't want to have children for a large chunk of time. Clicked some sweating and thrush as side effects, but can't be certain they're due to the coil or due to hitting mid-thirties, ha!

Mirena coil  

I'm hypermobile, and over time it has made my symptoms a lot worse despite my levels of exercise to strengthen. I'm now in pain regularly and sometimes struggle to sleep because of it. I've also started having migraines with aura and frequent headaches. Getting it taken out next week. It did however reduce my heavy bleeding to infrequent spotting, but I bled for 9 months straight after having it inserted.

Mirena coil  

I love my hormonal coil. I have had no side effects what-so-ever and my bleeding is regular but extremly light, only monthly spotting. I did have ongoing spotting for around the first 6 months but no issue at all since then and the spotting was worth it for the final result of minimal bleeding.

Mirena coil  

Expressed concerns as not very tolerant to pop pills, was told it’s localised so wouldn’t be the same. Insertion caused intense one sided stabbing pain. This cramping then continued for the 6 weeks that I tolerated it, especially after eating. Bleeding and spotting was literally all day everyday. My moods worsened, anxiety went through the roof and I felt horrible! Didn’t have sex at all with it in! Asked to have it removed and gp ignored me. Arranged appointment with sexual health clinic, 4 week wait. You are at their mercy for removal, no control of your own body. Luckily an amazing nurse who could see the distress it was causing me. Instant relief once removed. Mood lifted and amazing not to be bleeding every single day. I couldn’t have waited out the 6 months, if I could I would have removed it myself.

Mirena coil  

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.

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.

Mirena coil  

Got this inserted as a long-acting, reliable method of contraception. I found the insertion process ok, it was uncomfortable but not painful. I was able to easily feel the coil threads when I checked regularly. I had lighter periods but actually found period pains worse with the coil in place - hence the deducted star. I had this removed as we wanted to try to concieve. The removal process was totally painless. We got pregnant in one month of trying.

Mirena coil  

From coil insertion I had issues, it was very painful having it inserted and I had cramps for a weeks. I also got a post coil infection. I would get horrible period pain at that time of the month and my periods would also last longer than before coil. Often had spotting and could always feel there was something there like a pressure (difficult to explain). I also didn’t feel like myself, I didn’t have energy for a long time after the coil insertion. I got thrush and then got a UTI in August which I had for 6 & half weeks and took 5 courses of antibiotics. I finally saw a nurse who said stop the meds and agreed with my decision to have coil removed and said we would monitor it. I had coil removed 29/09 and am still getting the discomfort down there and regularly have a hot bean bag on my lower abdomen. Some days are better than others and this week I have had headaches so I’m not sure if it is linked to coil removal. The nurse will call me for follow up next week and if still getting it she needs to see if it could be pelvic inflammatory disease

Mirena coil  

I liked that it was minimal effort once inserted. My periods were far lighter and less frequently occurring. Because of the thickening of vaginal fluids being part of the mechanism; I found I because much more prone to UTIs after sex and also had lower sexual drive. I came off the Mirena because I wanted to track my cycle accurately to see if my hormones and cycle were affecting/triggering my seizures (I have drug resistant epilepsy). When I came off the Mirena I found I was less anxious over the months following swapping to the copper coil I.e. non hormonal. This had not been a concern of mine when on it.
