Mirena coil has an average rating of 3.5 out of 5 stars from a total of 559 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.

Generally the Mirena has been great. Only noticed most of the side effects after 4 years having it in - and they’re still very manageable.

Mirena coil  

I had the worst time on Mirena. I had a bad experience from day one at insertion - I found the whole experience so much more painful than I imagined that it would be - no one really prepares you for this. From the first day I started experiencing cramps and everyone said that they would ease up within no time however they did not. Month after month I experienced endless painful cramps and times where I would be doubled over in two on dates with my boyfriend - never have I had anything like that. As a girl, we very much always shut up and put up and I always felt like I could just push through it but there were times when it was really bad and I almost got it out, but you’d forget about it the next day as it’s such a good feeling to not have to Take a pill etc and it is very convenient. But it’s also crazy I actually had it in for as long as I did. I have never really had that bad periods and my bleeding was longer, the cramping much more intense and honestly just a whole lot worse than it was when I was off it. I didn’t really notice anything kind of sexually or from a weight or ski. perspective but I know that the cramping and the bleeding was enough for me to never touch this thing again. The Doctors kept telling me to hold out and just wait to see if it would change and it just never did. I would really recommend if you are having these symptoms any time past two months they are not going to get better and you’ll just continue to suffer. At the eight month mark I went and got it out and honestly it was the best thing I ever did. As soon as it was out, I felt like I could actually breathe again and havent suffered another cramp like it ever since (thank god!). I have gone back onto the mini pill now which I’m much more happy with - it does have some side-effects but nothing like that cramping!

I feel like myself, which I cannot say for other forms of BC I’ve used. The weight gain may have more to do with some lifestyle changes, but I enjoy the way my body look regardless. I was able to collaborate with my doctor to find suppositories to help with the dryness during sex and that in turn has helped with my libido. I cannot imagine using another form of birth control.

Mirena coil  

I've not had any significant side effects...so far. But the one thing I don't like is that I struggle to track my period. I don't bleed it bleed very little. Some periods are just spotting. In theory this is great, but the rest of my body is still experiencing a cycle and without the bleeding it can be hard to track. I still try to, but I'm about ready to give up. If you are like me and spent 10 years on the pill, this can feel a bit jarring. I'm on a hormonal rollercoaster that is normal but I'm not really use to it. My cramping is normal compared to before I had coil. I've had acne rosacea crop up and after a year of it I strongly thing it's linked to hormones but not sure how much the coil plays a part (though I did NOT have this before coil, I am also 40 and may be perimenopauseal). Insertion recovery was totally fine. Very little discomfort. However I was undergoing a minor gyno procedure at the same time and as a result got a general! Highly recommend should it be available. Won't lie, not sure I would have the coil again after this one....I'm still not sold in all honesty. It just emotionally felt evasive as a method of BC.

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.

Mirena coil  

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.

Mirena coil  

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.

Mirena coil  

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.
