I am a new user to the copper coil but am happy with how its going. I naturally have heavy periods (day 2 i would go through 4 pads extra absorbant in the day) but I'm in a place where i wanted to allow my body to heal after over 10 years of progesterone contraception ( implanon-mirena- copper coil). I feel this is a good balance for allowing my body to live in its natural state while also protecting from conception.

My experience with the copper IUD happened over an 8 year period. Had my first copper IUD for 5 years, ages 19-24, was perfect, periods were heavier for around 3 months but went back to normal. No pregnancies, no pain, literally was a miracle contraception for me. Lost my IUD card so was not sure if I had a 5 or 10 year coil, clinic is impossible to get in touch with, so I thought I would get it replaced just in case. After replacing it I had horrible cramping, periods so heavy I would see stars, pain not only after sex, but after masturbating no longer than 2 mins. 6 months into my second IUD I went for scans and check ups as the pain was not getting better, everything seemed to be in place. Went to the clinic for a consultation and they advised get rid of it or go for the Kyleena. Got the Kyleena IUD which was amazing until I fell pregnant after having it for a mere 11 months. Terminated the pregnancy and went back to the copper IUD. I had three copper IUDs (YES 3 separate insertions) due to two of them moving out of place. All 3 of them gave me insane amounts of pain, WAY worse than the 2nd IUD, I’d get cramps going to pass a bowel movement or even overeating. Got this last one scanned and checked out due to the pain that was not subsiding, everything was in place, decided to leave it in despite the pain for another 3 months as I just really wanted it to be like the first one. After 3 months I was so depressed from how much pain I was in, I got it removed and now I am pain free. Giving this three stars because my first IUD was the best and I wish I could go back to it, the other 4 were seriously having an impact on my life and mental wellbeing, I spent a whole session with my therapist talking about my traumatic experience with this bloody thing. Please note I am an anomaly, but if you have it and the pain is not subsiding, do not hesitate to get it removed, some people’s bodies (such as mine) just reject it for whatever reason.

I had break through bleeding most weeks for my first 6 months of this pill, then everything was great, however for my final 5 months of the pill I bled again every single day. I decided to come off as it was negatively effecting my mood from the bleeding and also felt zero emotions towards sex or excitement - just felt generally 'meh'.

I went on desogestrel twice. The first time I noticed it made me cry extremely easily, and I bled pretty much constantly for 9 months. Then I came off it. When I tried it again for a few months, I had a similar experience, with the added side effect of being so hungry that if I wasn't constantly snacking I was insanely nauseous. Ultimately, it was the bleeding that made me stop it.

I have never been this overweight in my lifetime... Always been a size 10-12, I'm 50yrs old and started taking these at 48 yrs old due to falling pregnant unexpectantly... however this was the worst option I took as I gained over 20kgs in weight. I went from 80kgs to 106kgs

I went on Slynd to help with endometriosis, but unfortunately I developed a wide range of side effects that made me stop. The most unusual one was nerve-like stinging pain after sex and orgasms. Even though I stayed lubricated, I would get a burning/nerve pain that lasted for days afterwards. Alongside that, I also experienced dry mouth, chest pain, insomnia, low mood, low energy, acne, dry skin, anxiety, and frequent headaches. The combination left me feeling really unwell, physically and emotionally. I wanted to share because painful orgasms and these systemic symptoms weren’t something I’d ever read about with Slynd, and if anyone else is going through the same thing, you’re not imagining it

I stopped taking the pill yesterday. I used desogestrel for four months for my endometriosis. I tried really hard to stay positive, to remind myself that it takes time for the side effects to go away and for my endo pain to lessen. Well, unfortunately desogestrel hasn't helped at all, but has made everything worse for me. I've gained 5 kgs in these four months. I've always been naturally skinny and never gained (or lost) weight, so gaining this much in such a short amount of time is a lot for my body and self-esteem. Most of my pants don't fit anymore. Sure, some of it is just endo bloating, but the weight gain does play a part in it. And then there's the hot flashes. One minute I'm sweating like crazy, the next I'm feeling cold. I've also had constant breakthrough bleeding, so I'm using pantyliners daily. For the last two months of using the pills, I've had my periods every other week, which means I'm in terrible pain more often than I was without the pills. That's why I finally decided I've had enough and stopped taking desogestrel. I can't stand all the side effects and the pain. But this is just my experience, the pills might work for someone else! :)

I used this for a month hoping it would help with period cramps. Do not recommend. I used it perfectly and felt nauseous everyday after taking it. I got a 9 day period (with cramps) during what was supposed to be my "ovulation" week.It had me feeling very anrgy, caused me period like pains and headaches daily.

In general I had a good experience with Slynd. It helped my underlying endometriosis significantly and for the 4 months I was on it I had no period cramps or pain for the first time ever. Unfortunately I had to stop taking it because I was spotting everyday. I thought my body needed time to adjust but after 4 months I was still wearing a pantyliner every day. It was very minimal and I had no pain but I just didn't want to wear liners every day. Once I stopped Slynd I went back to 'normal' after about 3 days but sadly my periods are back to being painful. As an aside, I noticed a reduction in sweating whilst on Slynd and several days I would go without antiperspirant or deodorant.

Great pill been on and off twice for a few years, no side effects bar really really really tender and sore and sensitive breasts. I have such bad health anxiety and honestly this had my questioning if I needed to go to the doctors because of the scary big C that’s how sore and tender my breasts have been, can’t even lie on them.

Went on this for fibroid heavy bleeding and period pain. Have daily bleeding and spotting since starting, and periods are now more irregular and as heavy as before. It didn't help with pain at all. Im going to finish out this month's pack and go off them. However, I got some acupuncture two weeks ago and the pain during my period this month has been greatly reduced. Would reccommend trying it!
