Prior to having the mirena coil I had the most horrific periods literally to the point of passing out. I can say I have had my coil in for nearly 6 years and not had a period since and now I feel like I have my life back! It has been one of the decisions I have ever made and also hardly had any hormonal side effects.

I loved the mirena but over 3 different coils, shortly after insertion I would get kidney infections that didn’t respond to antibiotics. The link was only made on the third despite me asking the gyno about it. Such a shame because I loved it otherwise. Kidney infections mostly skipped the uti stage and went straight to them but bacteria wouldn’t grow in pee. If this sounds like you remove it!

I've had the mirena coil for four months, I'm still bleeding irregularly (period every 8 days) and lots of spotting. I've been dizzy for months, I'm feeling very low, I have water retention and a lot of lower back pain that feels like a pinched nerve so I'm battling to concentrate on work. I really want to have it removed but I'm terrified of going back to the alternative of extreme heavy periods that made me anemic.

I've had great success with a Mirena for treating jawline acne, after getting it to prep for going onto Roaccutane it actually cleared my acne up amazingly and now I just get the odd spot every month when I'm due on. I get irregular, yet light periods, and occasionally some spotting, and overall my period cramps have been lessened. My sex drive is not what it is when off hormonal contraception, but as I've been on hormonal contraception my whole adult life, bar a couple of years here and there, this hasn't been an issue overall. I have put weight on gradually, but I've also aged (now 34), so its more likely to be metabolic changes rather than a side effect. The only thing I would say is that the coil itself has moved twice, resulting in removal and replacement (I'm waiting for another removal, and will likely explore pill options again as its just too painful getting it replaced every 2 years!). It should last 8 years, but for whatever reason, maybe my anatomy, mine moves to be too low, and then the long process of getting it checked, ultrasounds, appt waiting times for removal, and everything else, means its not something I want to continue using at the moment. Overall though, it has been a really good method for me, and just because mine hasn't stayed where it should be, doesn't mean someone else won't have a good experience, its probably down to my anatomy only!

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.

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.

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

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).
