Mirena coil has an average rating of 3.5 out of 5 stars from a total of 591 reviews when used as a contraceptive. These are self-reported reviews where users of Mirena coil review their satisfaction with this contraceptive and any side effects they feel they experienced whilst using.
Mirena is one of the most popular hormonal coil brands and is adored by many healthcare professionals for it's benefits. Like all hormonal coils it releases a low amount of progestogen into your womb, meaning low levels circulate through your system - this may be why most women experience few side effects. Plus many users have lighter bleeds or even no periods - which is why gynaecologists love it. Once it's fitted, the Mirena coil can be used for up to 8 years for contraception if you are under the age of 45. If you have the Mirena inserted over the age of 45 it can be used for contraception until the age of 55 without the need for replacement.

Mirena coil  

I was very worried about trying this method as I’d not used hormonal contraception before but overall it has been positive. The insertion was quite painful but not unbearable. It took about a week for me to recover, with me having to stop exercise for that time and then slowly increase again. Bleeding has been the most annoying part as my periods are very irregular now (previously they were regular as clockwork) and I have light spotting for up to a week before each period. But it’s getting slightly better each month and I’m hoping I’ll be one of the lucky ones who eventually gets to little or no bleeding at all. I’ve suffered no other symptoms of note.

Mirena coil  

I've had the hormonal mirena for 14 months now to reduce endometriosis symptoms. My periods have reduced in length (used to be 3 weeks) and happen irregularly and the pain has settled during these. I have however noticed continuous weight gain since I went on it, despite very little changing in my diet and exercise. I've always stayed at a very stable weight and now my breast have nearly doubled in size and my weight in general continues to creep up. I have tried upping my exercise with no improvement in my weight. I'm the heaviest I've ever been, except for pregnancy. It's a huge price to pay for a reduction in endo symptoms. It's very frustrating.

Mirena coil  

The insertion process wasn’t pleasant and I found very painful however I will say it was very quick and the pain didn’t last. After leaving the doctors I felt fine apart from a little light headed but that was due to me stressing. The next day if I didn’t know if had it fitted I would be none the wiser as I felt normal and had no issues. Since then I have really liked not having to think about it, I had no periods at all but have started to get a day or so of spotting once a month at the 18 month mark and some light cramps. The only other negative to me is that it’s meant that I now always have to use lube for sex as it’s definitely affected dryness. The best overall contraception I have tried

Mirena coil  

Such a hideous experience for me I went to the doctors to get it taken out ASAP. Had severe mental health dip and felt suicidal which was really unlike me. The pain on inspiration was absolutely awful (removal was easy and painless).

I’ve had the mirena in for almost 2 years and it’s been working great as a contraception and minimal side effects (very light periods).

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.
