At first all the skin problems I got from it scarred me. But I first started Jaydesss becuse of extremely painfull periods. This absolutely helped, I mostly lost my period which I thought I will never be lucky enough to experience in my life. The skin problems got a bit less annoying and extreme after I lost my periods. But at first I had really painfull pimples all over me - my face, chest, back, especially back on y neck and under my hair - on my head (i never had that before ever). Later I only experienced a few shoulder and face pimples. Since my period is gone, my back pain and cramps are gone completely. I am so happy and I feel like I no longer have to fight a battle with my body every month. I am a happier person, I feel mentally healthier. Before that I was scarred what the month will bring with body pain and how I will hide blood stain that was everywhere, ruining my clothes, bedsheets, even towels. There was so much blood and now there is none and I feel lucky :)

I love this coil! I was keen to have a copper coil initially but as I already had quite painful periods I was advised against this and I love the Jaydess! Initially I had some spotting after insertion but my period / ovulation dates are the same (I was tracking my cycles before) the only difference now is that my periods are lighter and a bit longer than they were previously (before they were 3 days and now about 5-7 days but about 2 or 3 of those is just spotting). They are also generally less painful (although the pains feel different - more like the deep cramps you get when the coil is inserted rather than my old period pains). I really like this coil and it is very low hormone so haven't really noticed much in the way of hormonal side effects - my boobs get a bit more tender pre period and I think I might have had like one more spot than is usual for me but that also might be diet related! I haven't noticed any bloating or weight change! It's really really good and I reccomend it!

I’ve had this coil in for around 5 weeks now which isn’t a long time but it’s the best i’ve used so far. I have had positive experiences with copper IUDs in the past but they have all rejected due to strong period cramps, so I decided to give the Jaydess a try as it is the lowest dose of hormones available. I initially had it inserted a week after my period and the following week I started my period that lasted 17 days, very heavily. I didn't have any mood swings or weight gain in that time, but the cramps were SO bad for the entire time. On the weight gain, my experience might be skewed as I go to the gym and do very rigorous cardio 6 days per week. I have ultra dry skin also, so I cannot comment on acne as I luckily don’t suffer from it, apart from one super huge spot that came up on week 4. So far so good girls, stay safe and good luck!

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
