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.
Decreased sex drive

So I’ve had the kyleena put in just over 2 years ago. For the first 18 months it was great, there was no side effects and my periods were getting lighter and less painful! After that, I started noticing quite a bit of hair loss during showers and brushing, visibly making my hair look thinner. I’ve always had thick hair so this was quite upsetting and I put it down to the stress I had during college. Now I’m in a new job that I’m loving, the hair loss hasn’t subsided. It’s still falling a lot everyday so I’m deciding to get the kyleena removed in a months time. I’ve been to the GP and got bloods done in which everything came back fine. So hopefully once I’ve the kyleena removed my hair will slowly start growing back :(

Not 100% sure what to think yet. Enjoying not having to worry about administrating my contraception as it’s in there and working. However I am having unpredictable spotting, some emotional mood swings and often being bloated.

Used for over 10 years, completely stopped my periods which was fantastic. The devices became harder and harder to use, needing a lot of force to inject so I ended up turning myself into a pin cushion & wasting a few, which made reordering a faff. Don’t think I gained weight and if anything my skin improved (but that could just be normal from teenage to late 20s). The only negative I noticed was decreased sex drive - but it didn’t totally go so not a massive issue for me.

I was on this injection for 2 years, the whole process put me off . when i started the injection i had a period of 16 days (over two weeks) and it was so heavy, months went on and my periods stopped all together, i didn’t have a period for minus 2 years , i’m now on the combined pill but i did receive higher anxiety and depression towards taking it for ages, the doctor offered me antidepressants but i didn’t want to be taking them as i am a quite smily happy person but i literally lost all my energy and motivation to do anything.

I like the injection as no periods at all but gained over 2 stone in weight and no amount of dieting, eating less or exercising helps loose any weight at all I just gain even more.

I didn't notice any changes at first. I got my period for the first month or two, then the bleeding was irregular and lighter and eventually it stopped completely. I gained weight quickly. I would get hungry even after eating. I would get severe vaginal itching a few days after the shot.

It is effective and it's convenient but unfortunately the side effects are really bad but it depends on different body types

This is pretty good for preventing pregnancy and my periods are thankfully gone, but now I have acne after having years of clear skin. It’s hormonal acne too due to the progesterone in the injection, so a nightmare to get rid of. I was prewarned about this issue but still hate it. I feel like my mood has gone lower too and I am more irritable than usual. Unsure whether I’ll get it again I will probably go back to the Lucette pill as that completely cleared my skin.

Caused me horrendous hunger such that i couldn't feel satisfied with any amount of food. It was terrible for me. And the side effects continue even after stopping. It was my first time in 11 years to back to hormonal contraception and l will never ever do it again. I only go non hormonal. I honestly can't take the risk.
