Random cramps throughout the day, they suddenly stop and start again a few days later. Period almost completely gone, but random spotting through ovulation and calculated period days (on clue app). Very bad breast tenderness during ovulation and periods

I’ve had the mirena in for almost 2 years and it’s been working great as a contraception and minimal side effects (very light periods).

I'm on my second Jaydess (been using it for almost 6 years now), before I was on the pill (estrogen+progesterone combination) for about 6 years. Insertion is no fun for me, other than that I can only recommend it. Compared to the pill I have much lighter periods, period pain has significantly decreased (I get a little abdominal discomfort+back pain a day before the start of my period, and that's it). Acne stayed about the same as on the pill. I get a little breast swelling/tenderness for about one week every cycle which I think has slightly increased compared to the pill but isn't so bad. Sex drive and mood stayed about the same, if anything, my mood has become more stable on Jaydess actually (but that could also be attributed to me growing up I guess). Overall I'm satisfied with it
Very positive mood

I got the coil after having a failed mirena coil. Tried this one for almost 3yrs and didn't think I had alot of side effects, though reflecting on a time where I was not on contraception, I realised it had greatly impacted my moods and caused quite bad acne on my back, which I had never suffered with previous. I also would get debilitating cramps during my periods again which I never suffered with before. Only bonus was my very heavy periods were light, which made them way more manageable. I decided to get it taken out when my moods were having an adverse effect on my relationship and life.

Insertion of the jaydess for me was incredibly painful and i had severe period cramps the days following insertion. Other than that for the first year i had no symptoms other than tender breasts and they had grown from C-DD (no complaints!) and often reccomended it to friends. However, after that i started getting regular thrush. It started off just coming before my period some months but now it is pretty much constant. Treatment only resolves symptoms for a short period and the its back! For this reason ive booked to have it taken out next week. Also the waitlist with my local clinic is so long ive been on it months and am no where near being seen so have had to go private unfortunately as the symptoms hae become unbearable :(

After taking the pill for at least ten years I thought it was time to reconsider my options. Used the Lowdown to eventually choose the hormonal coil. Insertion was uncomfortable but nothing unbearable (for me, I know alot of people have had horrid experiences). My periods are very irregular (think maybe four a year and more spotting that bloody). My hormonal state throughout the month is more consistent, no major ups and downs than I used to get on the pill. I couldn't fault this as an option and also not having to remember to take the pill everyday was a huge bonus. Recent changes to the length of time for changing them meant I got an extra two years out of mine. Great long term option if you know you don't want to have children for a large chunk of time. Clicked some sweating and thrush as side effects, but can't be certain they're due to the coil or due to hitting mid-thirties, ha!

I'm hypermobile, and over time it has made my symptoms a lot worse despite my levels of exercise to strengthen. I'm now in pain regularly and sometimes struggle to sleep because of it. I've also started having migraines with aura and frequent headaches. Getting it taken out next week. It did however reduce my heavy bleeding to infrequent spotting, but I bled for 9 months straight after having it inserted.

Had kyleena fitted on recommendation from my doctor due to severe painful heavy periods, I have adenomyosis and suspected endo. Insertion was uncomfortable but not excruciating, the cramp lasted a couple of seconds and I was fine. Bleeding started within hours and didn't stop for the duration of use, I was having excruciating pain every day to the point I couldn't walk, feel my legs and awful tail bone pain. I booked an appointment a month later and my doctor said I didn't look well and removed it without me even having to ask. I wish it had worked for me but it just didn't. The removal was fine and gave instant relief.

I had used the Mirena coil back to back post partum for 9 years very happily but my LEA meant I was only having withdrawal bleeds. After restoring bodyweight and menstruating naturally, I went back for Mirena but was given Jaydess. The insertion was more problematic and that she how I ended up with Jaydess over Mirena. I had irregular and more bleeding for the first 3 months but read the reviews on here to help me persevere. I was “angry” as on Mirena it was always so easy but then I wasn’t actually properly menstruating due to low energy availability (eating disorder) so I drew perhaps FALSE causation on Jaydess being wrong. I have very light but regular periods and my PME is definitely reduced. I’ve had it in a year and am very happy with it and my threads have stayed in place despite roughhousing which wasn’t always the case with the Mirena. I’m in no rush to have to it out even though I turn 50 this year.

Had this for adenomyosis and the pain stopped for a while but its back again now so the side affects aren't worth it for me. Having it removed later today
