I had the Mirena Coil put in for endometriosis. The actual insertion went well because I spoke to my gyno and asked for it to be done in the hospital, meaning that i had the option for general anaesthetic, local anaesthetic or gas and air. I went for the local and gas and air as I had had such a terrible experience having a copper coil put in 5 years prior. The gas and air distracted me and the previous coil removal and new coil insertion wasn’t much bother (i deliriously thanked the team in the room for not giving me as much trauma as the clinic i went to for my copper). The pain after insertion was significant but if you just prepare to have a day or two sat on the sofa taking regular painkillers it’s ok. After the insertion i almost instantly noticed a massive surge of hormones which my gynae had warned me about (she said i might feel ‘weepy’ for up to 6 months as if that isn’t a significant side effect lol). In the end I had major mood swings for around 4 months and was very irritable and all over the place. It did really damage my relationship as it was like i was having PMS every day. I wasn’t depressed or anxious, I just felt like i wasn’t in control of my emotions and i honestly felt like a hormonal teenager who is happy one minute and then angry and upset at something the next. (i also got a bit spotty in the first month or two after insertion - but this cleared up) Eventually after 4 months the mood swings stopped and I can honestly say Mirena is SO WORTH IT if you suffer from endometriosis. It’s completely stopped my endo pain to the point where i don’t even notice my periods anymore. Honestly Mirena gave me my life back within weeks of insertion. After suffering from daily pain for 5 years I now have so much more energy, my chronic fatigue is gone because the pain is completely gone and feel like i’m finally living again. I can make plans, hang out with friends and go into the office regularly - it’s helped me thrive again. It makes me sad that i wasted so many years in pain when this was an option and i would 100% recommend it!! I was initially hesitant to get Mirena because i was worried about the hormones affecting my mood and skin etc as im so susceptible and felt like a different person on the pill. But the important thing is that after the initial hormone “surge” you feel normal again - you just have to wait it out and hope that people around you will be patient with the crazy mood swings for a a few months. If you suffer from endo you will hopefully (everyone’s different) have the silver lining that you’re not in pain anymore so you gain a lot of energy that counters the mood swings. If you have endometriosis or even suspect you might have endometriosis I would really encourage you to get Mirena put in as a first port of call to try and treat it. In terms of my periods they’re SO light - literally just like brown spotting which i barely need a panty liner for which is amazing. sometimes they’re a bit irregular and can last a long time but honestly they’re so light i forget my period exists and Ill confidently wear white trousers whilst menstruating (it’s THAT light) The only reason i’m not giving 5 stars is because several months of feeling absolutely mental is not ideal BUT the level of freedom, energy gained instantly, lightness of period and now lightness of mood now i’m out of the surge period made it all worth it
Very negative mood

I generally had an okay time with it but i kept getting spotting/or a light period every couple of weeks. much lighter than a normal period would be and without the usual pain i would get but definitely more frequently - which i found frustrating, and was often very bloated because i was so regularly getting a short period, it was quite annoying, so i stopped. I also thought it was making my hair shed. it was always pretty uncomfortable putting it in

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!
