Kyleena was recommended with mr having Adenomyosis due to wrongly being given the copper coil before and bleeding for months on end. Kyleena had irregular periods to begin, the only sidr effect for the first 4 months were severe coldnesd/flu like symptoms the day before my period for all 4 months. As my periods stopped, my sex drive and mental health crashed. I'm on month 9 and awaiting removal.

Having used the pill on and off for 20 years I was hesitant to use another hormonal contraception but I was so happy with kyleena - no noticeable mentsl or physical symptoms. Insertion is not pleasant but it's over in seconds.i experienced some period cramps in first few weeks but then periods became extremely light and pain free for the last 3-4 years. I would get this method again without hesitation.

I had a terrible experience with Mirena. It started with severe cramping after insertion. The cramping continued for weeks. I got a UTI from it. Then the other symptoms started - severe depression, sneezing, severe sinus pain, insomnia. I experienced severe vaginal dryness and vulvodynia (shooting pain down there) which ultimately led me to showing up at my gp and begging for it to be removed.

Periods stopped, no noticeable side effects other than toward the end of the 5 years when I had a few side effects (tender breasts, spots, mood swings) which I put down to hormonal change as the coil was coming to expiry date. Now I've had it replaced and I have no side effects. Stable mood, skin clear, no periods, no stomach/back/head pain.

In terms of contraception practically perfect, I react extremely badly to hormonal contraception usually and this didn’t cause any of the negative side effects I usually get from hormonal methods. My periods became lighter and I still have the normal symptoms of my cycle which is exactly what I want. The only negatives (which is quite a big one) is significantly increased pain throughout my cycle, during my bleed and also cramping randomly throughout the month, sometimes when exercising and also two days before my period which I didn’t experience before. I am devastated that this has been discontinued in most places. I think it’s completely inexcusable that there is now no IUS which for most people doesn’t stop their period. One other slight negative at the beginning was my partner took some time to get used to the feeling of the strings when having sex, however this improved after a few months and is no longer an issue.

Got this inserted as a long-acting, reliable method of contraception. I found the insertion process ok, it was uncomfortable but not painful. I was able to easily feel the coil threads when I checked regularly. I had lighter periods but actually found period pains worse with the coil in place - hence the deducted star. I had this removed as we wanted to try to concieve. The removal process was totally painless. We got pregnant in one month of trying.

Overall my experience has been positive in comparison to my previous experience with combined oral contraception. I no longer have mood swings or night sweats however over the 4 years of having my hormonal coil I now have no sex drive which was a big change for me, in addition to this sex became painful.On the other hand my periods stopped after 6 months to a year.

Today I finally had my Mirena coil removed. The insertion and removal went smoothly and were painless. I had the coil for 10 months. During the first 6 weeks, I experienced continuous bleeding. After that, my periods became more regular but were very long up to 10 days and lighter than usual. After a period ended, I had another one a week later for only 3 days, and then the cycle repeated exactly every 28 days. I also had persistent discharge, infections, and cysts, and I even had to have a biopsy due to white spots on my cervix caused by the Mirena. Today, having it removed, I felt immediate relief. I was prescribed desogestrel tablets, so hopefully it will be better, although the pill doesn’t have very good reviews either.

From coil insertion I had issues, it was very painful having it inserted and I had cramps for a weeks. I also got a post coil infection. I would get horrible period pain at that time of the month and my periods would also last longer than before coil. Often had spotting and could always feel there was something there like a pressure (difficult to explain). I also didn’t feel like myself, I didn’t have energy for a long time after the coil insertion. I got thrush and then got a UTI in August which I had for 6 & half weeks and took 5 courses of antibiotics. I finally saw a nurse who said stop the meds and agreed with my decision to have coil removed and said we would monitor it. I had coil removed 29/09 and am still getting the discomfort down there and regularly have a hot bean bag on my lower abdomen. Some days are better than others and this week I have had headaches so I’m not sure if it is linked to coil removal. The nurse will call me for follow up next week and if still getting it she needs to see if it could be pelvic inflammatory disease
