Caused increased anxiety, extreme cystic acne that did not respond to prescription acne treatments, and severe hair loss. Made my periods longer and heavier at first, then they finally started getting lighter but I was still spotting almost every day. Gave me hot flashes badly.

Didn't use it long enough to really form an opinion yet, but the reason I got it in the first place was because of very heavy periods and cramps. It has helped with that.

After 14 months I pretty much don't have a period, but I still have light to moderate cramping a couple of times a month.

Great experience, insertion cramping was minimal. Got pregnant 4 months after removal.

Getting it in hurt briefly, but tolerable. The first period after getting it was early and super intense, and I continued having spotting most days for the first three months or so, but bleeding dwindled over time and by a year later I was barely getting periods at all, which was great.

I have been on kyleena almost 5 years, January 2025 it will be 5 and little to no problems. But I didn't know there was a mucus discharge, had thought I always had a yeast infection. Almost time to get a new one and I've started spotting again.

I could feel it when I exercised always. Starting year 5 I had terrible cystic acne and lower back pain that travelled down my left leg to my knee. It’s been 4 days since it was removed and my back is already feeling better. A heavy period starting the night I had it removed. It’s been going on 4 days and it is still heavy. I am hoping the acne goes away over time since it is out. It was nice not having heavy periods but not at the expense of my face and back. I have had to see a Dermatologist for several years now and the treatments don’t help much. I also saw a back doc and had a shot to help with the pain along with physical therapy for a few months. The shot helped for a month or two but the pain returned. I gained weight because it was uncomfortable to exercise and feel the IUD even when I walked uphill and the back and left leg pain. Insertion was traumatizing and I was conscious sedated for the removal which was a much better experience. Women should not have to go through that without conscious sedating. We should also be provided with more info on what to expect when we get it, how it might age, what to look for side effect wise, and guidance on getting it out and the aftermath. Terrible experience

Overall I really disliked this IUD. The insertion was extremely painful. I experienced spotting everyday for 6 months. When I started to get monthly bleeding again I would get debilitating cramps that caused me to miss work and school.

I got my first Mirena when I was 17. I would describe the insertion process as uncomfortable but not painful. I did have a vagal response (came close to passing out) right after, but it didn't last long, I just needed to sit for a minute. I experienced very light cramping for about 4-6 days afterwards. I did lose some weight that year that may have been attributed to the birth control, I went from 120lbs to 100lbs (there were no other pressing reasons for the quick change in my weight other than the BC, perhaps stress as it was my senior year of high school). At the time, the Mirena was thought to be effective for five years, so I had it removed and replaced with another Mirena when I was 22. The removal and reinsertion was more uncomfortable than the initial insertion, but totally manageable in my experience. Overall, I did not experience many hormonal side effects that I noticed. I pretty much stopped menstruating after the first few months of having it, aside from very occasional, very light spotting. I would sometimes experience symptoms of PMS without the bleeding (a little fatigue, some mood changes). I did develop some cystic acne in the first 1-3 years of being on my second IUD, but it was truly not much and never lasted long. My favorite part of this method is how effective and easy to use it is. I was truly never concerned about pregnancy from 17-27 which allowed for a lot of freedom in terms of my sex life. In my long term relationship, we do not use condoms (both have been screened for STIs) and I feel completely safe and comfortable with my partner not pulling out (I know that's a personal detail but I what to emphasize that that's how effective it truly is in my experience). I did recently decide to remove my hormonal IUD and replace it with the non-hormonal IUD. My Mirena still had at least 2 years left in it, but since I had not had a period or had gone through that natural, hormonal process in 10 years, I wanted to give my body a break from hormonal birth control to develop that relationship with my body. If I did not have the option/privilege to change methods, I would have 100% kept my Mirena until it expired, and probably got a third one.
