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.

Levosert coil  

While I had my Levosert, I liked it. I had mood changes, and cried a lot more than usual, but mostly just leading up to my period so it was manageable. I had recurrent thrush with it, and actually ended up having a prescription for monthly fluconazole tablets. In the end, after around 2 years, my coil slipped into my cervix, and it was incredibly stressful. I had no symptoms that it had slipped down, except my strings were a bit longer than usual. A doctor mistakenly told me it was fine to keep using, but when I later had it checked at a different clinic with ultrasound, they were alarmed that I'd had no symptoms as it was pretty much almost out of my body. I'd essentially been unprotected for about 8 months, and this led to a big pregnancy scare.

Mirena coil  

The mirena coil did effectively reduce menstrual bleeding and prevent pregnancy. Due to thickening vaginal discharge I found I was more prone to thrush and also that this had an impact on arousal. I was an advocate for the hormonal coil until I changed to a non hormonal birth control and found that this had elevated my anxiety certain times in my cycle. I am epileptic without seizure control and this was my reason for coming off hormonal methods. Female hormones can trigger seizures in women with refractory epilepsy!

Positives: lighter pain free periods, no anxiety over remembering to taking a pill everyday, no changes to mood skin weight etc. Negative: it moved after 11 months and I fell pregnant

Kyleena coil  

I was on the Kyleena IUD for 10 months after being on mirena for 5 years. Kyleena has had a terrible impact on my mental health and the reason I got it removed was because increased hair loss.

Mirena coil  

Have only had the coil for 2 months (although feels like much longer) so will give it a bit more of a chance, I also acknowledge that everyone reacts differently and my side effects seem to be less common, however in my experience and at this point in time, the negative side effects FAR outweigh the positives. My GP talked me into trying Mirena for managing my PCOS and the excruciating pain I would experience on occasion from burst ovarian cysts, as well as the birth control aspect. I’ve gone from an abnormally long (but fairly painless) cycle to an even longer one, bleeding and in moderate-severe pain almost daily. If my stomach doesn’t hurt, my head will be, or both. I’m not joking when I say I look pregnant from abdominal swelling on top of it all.

Mirena coil  

It was a very positive as i was having irregular heavy periods And personally I had a much better libido When in the past, bloods tested low in testerol levels of 7.5 i II wish this had been aware of of this before bow, i thought there was something not quite right as apparently 12 or above is the better level of testerol for women

Mirena coil  

I've had the Mirena coil for about 10 months now, my doctor recommended it to stop uterine polyps from reappearing. Prior to the coil I had very heavy, extremely painful periods and pretty bad iron deficiency, but now my periods are super light and not painful at all!! The insertion was painful but not worse that the period cramps I used to get before; I spotted for 3 months straight but after that I started having semi-regular periods. I noticed that I had much more energy (probably because my iron levels were back to normal), my libido increased and I lost weight. I am really really happy with the coil.

Mirena coil  

Awful experience having it fitted, very painful. I’m convinced it triggered vaginal atrophy (I was already menopausal)
