This coil gave me really dreadful mood swings from ovulation time through to the start of my period. I felt really low and anxious, irritable with family, almost irrational about certain things, constantly crying, and passively suicidal. This persisted for around 8 months including months where I didn't have anything difficult/stressful going on personally. It clearly correlated with my cycle, and within a week of having it removed I felt like myself again. I know the hormonal coils work really well for some people - I have lots of friends who use them with no issues. But for whatever reason I am generally quite sensitive to medications and really noticed an effect from this coil. I've gone back to the copper coil which does make periods heavier, but I will take that over the mood destabilisation

for me it works great, but i have a feeling my sex drive changed plus also the intensity of my orgasm. But you know I cannot tell for sure that the coil is the causing this..

Positive - first one for 5 years, protected against pregnancy, stopped periods after about 18 months so saved money on tampons. No significant side effects initially. Set and forget method was great. Negatives - I found the fitting incredibly painful. When I had it changed after 5 years the reinsertion was traumatic and I won't have it again. I suffered with mouth ulcers every month that got progressively worse over time. My mood wasn't bad but it was overall flattened. The new one never settled and I had problems with the threads travelling upwards, I found medical staff across the board (GP, clinic, hospital for ultrasound) very uninterested when I had issues after fitting which was difficult because I was frightened of possible consequences if it moved or they couldn't get the threads to remove it. I have honestly never had thrush so much in my life as I did when I was on kyleena. Noticed more and darker body hair over time.

Works well for me, was hoping would take away periods altogether but definitely made them lighter. Found fitting comfortable as just had some cramping. But I have quite a low cervix, so I could feel the strings and needed them trimmed.

Not pleasant to put in but completely stopped by periods after few months. Reassuring that no pregnancy, however absolutely 0 sex drive and this effects relationships.

Initial 3 month settling in period is intense, lots of bleeding and emotional side effects plus insertion pain. After 3 months it settled and I thought I had found the holy grail, emotionally stable and no side effects. At 6 months I developed a large ovarian cyst which put me in agony and A&E, doctors said this was caused by the coil and had to remove it. Unfortunately I cant recommend, the search continues.

No periods but developed acne. I also get cysts now regularly (never had before) that burst and hurt so bad that the first time it happened I went to the ER.

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!
