Struggled to fit the Mirena & so fitted the Kyleena instead - potentially leading to an insufficient amount of progesterone as i continued to have irregular bleeding. After about 12 months this settled down and month on month this has lessened and my cycle continued. However, I experienced consistent cramping like I'd never had before and from 15 months onwards severe & debilitating pain about a week before my period. This is why I had it removed.

I've always had painful periods and the month before I got my coil, my period hurt so much I actually threw up and that's when I decided I would do something about it. I've been on the pill before (rigevidon/microgynon) but it negatively affected my mood, I had terrible anxiety and generally felt horrible all the time so I stopped. When I got the coil, the sexual health clinic I went to used spray anaesthesia, but it still really hurt. The thing is, it only hurt for about a couple seconds, where it basically felt like your insides are being crushed and you're having the worst possible cramps ever (x10). Afterwards, I had normal (period-like) cramping for the rest of the day but they gave me a heat pack which really helped. I had spotting for about 3 months afterwards (yes, every single day) but it was fine and after a while I got used to just wearing a pantyliner every day. I'm really glad my periods are very light now (I've missed it once only) but it's still there. I don't know whether it will disappear or not, but one of the reasons I chose kyleena over mirena is in hopes my periods won't completely disappear, just for peace of mind that I'm not pregnant lol. I have terrible breast tenderness sometimes, like it hurts to even touch, I can't tell if it's before I get my period or during ovulation, but it definitely appears once every month or so. My breasts didn't grow though so that's a bit of a disappointment compared to the pill.... All in all, I haven't noticed any mood changes, I'm still definitely very attracted to my partner, and he doesn't feel it during sex. There were a few times early on when he thought he did, but I got it checked and it was all good, I think he just had it in his head.

The lack of periods has been nice. But I experiences a dramatic decrease in sex drive from the moment it was put it and it takes a lot to turn me on. 12 months in, I noticed a lot of hairs drop happening and now my hair is notably thinner with a lot of breaks - I'm considering whipping it out.

Overall my periods were regular but once I got the coil I had very irregular periods and extra cramping. I also have frequent dizzy spells and headaches since it has been inserted. And I've seen an increase in spots and body hair since starting with the coil

Insertion isn't pleasant, but once it's in place, there's nothing to do for years! I had my first Mirena coil over 8 years ago and haven't had a period since insertion, only very occasional spotting (maybe once every 3-6months). I know some women like to track their cycle, but I never think about it and prefer it that way! Would recommend.

The threads disappeared on the first coil so had it changed early (wasn't great as they had to go digging about to find the threads). Had another put straight in at the time thinking it was a one off but the same happened with the second so I had it removed early as soon as I noticed them becoming shorter to avoid the first scenario again and switched to the implant. Great that my periods stopped on it and it's super low maintenance though.

Extremely painful insertion. Blood loss continuously for about 3 months, bleeding everyday. Then periods became irregular, passing clots the size of my palm. Periods worsened after merina, when ironically merina was prescribed for heavy periods. Dermatitis caused by merina after 2 months. Told that results with merina are variable, and to wait and see. Not good advice considering the health issues and extreme blood loss caused by merina so far.

The mirena coil stopped my periods and worked as a contraceptive, however it stimulated hair growth on my face which was not there before. As a result I have required many courses of laser. I do not have PCOS and have had testing, however I think the hormones in the mirena coil started the changes that are now continuing despite having the coil since removed. The coil was also extremely painful to have inserted.

Had the Mirena Coil in for around 9 months and it's made my periods so much lighter but a bit more irregular. It was really painful upon insertion and I'm still getting stabby cramps around when I should be having my period. Overall, I think it's worth it because my periods are so much lighter.

I had three Mirenas over the course of about 9 years. The first two were perfect, with no side effects and stopping my periods. For me the insertions and removals were fine. Maybe a 3 out of 10 pain wise and some mild cramps afterwards. Unfortunately I know that's not everyone's experience. After about 3.5 years of each Mirena, I got lots of breakthrough bleeding and my GP decided to change it early to prevent this. Unfortunately my third Mirena gave me unpredictable bleeding for months, which was affecting my life as I was always worried I'd bleed through clothes or during sex. I also kept getting recurrent thrush, which I'd not experienced before. For me another negative was that the strings always seemed to be really prominent and my boyfriend could feel them during sex. Overall a mixed experience - after years of hassle-free birth control I eventually changed to the POP due to the unpredictable bleeding I was getting with Mirena.

I found that when I got it inserted I had a light, almost discharge like period for 3 months and then once that finally went, I started having irregular periods and and someone whose always had regular periods this was infuriating. The reason I went on was for period pain and I found the pills, both mini and progesterone only, made my mood drop in terms of I was always angry and anxious and my general body image went on a downward spiral. I had no issues with the mirena up until about 3 months ago when all of this started happening again. I’m hoping this will help for others in my situation

Never having to worry about condoms is such a great plus. I had a lot of pain in the first six months and three 11+ day periods. Afterwards, my periods have stopped totally and I only get the occasional cramp, akin to an ovulation cramp. My libido has decreased slightly and my breast have gotten bigger. Overall it’s been a great help in my sex life
