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

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 really had high hopes that the copper coil would work for me, as in theory it sounds great! However, after a long wait and several appointments later. I finally got the copper coil inserted. However… two weeks later, the coil had to be removed, as it had moved down from my uterus into my cervical canal. Which can happen and is apparently rare! I was just unlucky. Due to me never being pregnant or giving birth (according to the GP) insertion procedure without anaesthetic was super difficult and quite uncomfortable for me. Luckily the GP didn’t push and force her way through my cervix and stopped the procedure after struggling for a while. The GP then referred me to my local sexual health clinic, to have the procedure done there instead. As apparently they have more facilities available and can apply anaesthetic to your cervix, in these types of situations. When I finally had the procedure done, it was a positive experience, thanks to the anaesthetic!!! It did hurt a little. The pain felt like a sharp period cramp that came and went! I wouldn’t recommend the coil personally, as in my experience it was a faff to get done and then only to have it removed two weeks later! Also, with how easily the coil moved! And the procedure being slightly painful, even with anaesthetic. All of the above is not ideal!

Insertion was incredibly painful. Was like a really bad first day of period that I had to take off work sick and take lots of painkillers for. Lasted about 24 hours then settled. Unfortunately cramps continued as coil had not settled properly and one of the arms got stuck in uterus wall so I had to have it removed. due to pain of initial insertion I did not want another one back in. HOWEVER SINCE GIVING BIRTH I had another coil fitted at 10 weeks post partum and could not feel a thing! I have the progesterone coil now and have not experienced any negative side effects, other than light bleeding for about 2 weeks after insertion.

I have previously been on the implant, the combined pill and the mini pill for many years and having to come off each for different reasons. I decided to go with the copper coil as coming off hormonal birth control it had felt so good to have my natural cycle back, but I’m not yet ready to have kids. Insertion: I went for a ten year one. The woman was lovely and talked me through the whole thing. It was painful - I won’t sugarcoat that - but it lasted only a few seconds. I had cramping and some bleeding for the next few days (had to use pads not tampons), but nothing too bad. After: I was really happy with my decision and most of the time forgot it was even there. It hasn’t affected sex at all. I will be really honest that my first period (and to a lesser extent my second) were really painful - much worse than normal and they do last a day or so longer. However now I’m 3/4 months in and they’ve returned back to normal on pain levels (just slightly longer as mentioned). I am back to ovulating normally (as I wasn’t when I was on hormonal contraception) and am feeling really happy with my decision to get the copper coil! It was very much worth the initial pain and a few painful periods for me. I like that I can now decide to just take it out if/when I want to have kids.

I got the copper IUD after 4 years of different hormonal pills as wanted to stop being on hormones. The fitting procedure went well, the doctor was reassuring and I had local anaesthetic so it was only a little uncomfortable. However the cramps afterwards were horrific - I was on the floor in tears with how much pain I was in. Painkillers and heat pads did nothing. This lasted a couple days then thing started to settle down until the cramps turned into a stabbing pain. Returned to the doctors, they initially said my symptoms were normal then checked my vitals before diagnosing me with a pelvic infection or Pelvic Inflammatory Disease (PID). I was on 2 antibiotics for a fortnight. The pain lingered but gradually got better after a month. I have just finished my second period off the pill. My period returned after 35 days of stopping the pill which was my old usual cycle. My period isn’t any longer than it used to be but I’d say it’s a bit heavier and more painful but definitely manageable. My moods have been so much better and predictable. My skin has gotten slightly worse as expected coming off the combined pill which helped my skin, but flare ups match up to my period so I don’t mind. I got the 10 year IUD but I don’t think I’d get another due to the worry of getting another infection but I am happy with it at last.

The IUD fitting itself was less bad than I expected, uncomfortable and a bit painful but not worse than period cramps. However, about half an hour or so after, I got quite intense cramping pain and almost fainted from it on the way home. The post-insertion pain settled after a few days. With the IUD, my periods were quite a bit heavier than before but this improved a bit after 6 months or so. With the IUD, I also got spotting between periods for a few days each month (possibly related to ovulation). Also, since having the IUD fitted, I started getting recurring sharp stabbing pain, always in the same spot on the right side (roughly where my right ovaries are). This pain was worst during my period, sometimes making me feel close to passing out even though I was taking the maximum daily dose of ibuprofen (I later switched to mefenamic acid but that was not much better), and it was much worse than any period cramps I had ever had and felt more like someone is stabbing me than like a cramp. I also had this same right-sided stabbing pain randomly throughout my cycle. Moreover, I also started getting cramping pain during exercise (running) after I got the IUD. The right sided stabbing pain and the cramps during exercise maybe improved slightly over time, but were still bothering me quite a lot after 9 months of having the IUD. I had several checks done to make sure the IUD was still in the right place and to exclude any underlying disease that could be causing the pain, but nothing abnormal was found that would cause pain like this. The doctor said that they could not exclude that the pain might be from a hormonal condition (like endometriosis) that was masked by the hormonal contraception (progesterone only pill) that I was on before I got the IUD. In the end, I decided to have the IUD removed to see if that would get rid of the pain, both because I felt that the pain was not something I was happy to tolerate indefinitely, and because I thought it would be important to know if I have something like endometriosis and this is what is causing the pain, because in that case I would have considered going back on hormonal contraception to slow it's progression (I wasn't happy with the side effects I got from two different combined pills and three different progesterone only pills, which is why I switched to the copper IUD, so I didn't want to switch back to hormonal contraception unless absolutely necessary). After I had the IUD removed, the right sided stabbing pain immediately went away completely, but I got the cramping pain during running once since - it hasn't been long since I had the IUD removed so I am hoping that this will eventually disappear too.

The copper IUD was great, I had it fitted and then didn't have to worry about contraception. However, the initial insertion was painful and it did make my periods more heavy and painful. I had the coil replaced after 5 years but this coil came out on its own. I do use a menstrual cup and the coil came out in the cup, so this could have been down to user error on my part.

the inserction was painful and invasive, it had me feeling faint that day but come sugary drink helped. i enjoyed my time with it, but my period was much heavier and it led me to iron deficiency. i decided to take it out recently as i wanted to know how it was without anything and i was concered as to whether it was a healthy option for my uterus. when i got it removed i did feel a very positive feeling from not having it, but that could be that it was a concern on my mind for a while. but now im reconsidering having it inserted again since having no birth contol isnt a great option and i think i prefer iron deficiency than hormonal mood swings with a hormonal option.

My experience of the copper IUD is mixed, even if overall positive. I first got it as emergency contraception after my first sexual experience, and was not properly offered any pain relief. The pain was excruciating and slightly traumatic, but also as I wasn't used to things going inside my vagina either. However it served me perfectly for 5 years, and no hormones and side effects from those. When it was time for renewal I was prepared emotionally and knew what pain relief to ask for. The procedure itself was quick and felt very empowering. They offered me the 10 year one which was slightly bigger and I thought it was no big deal. I was in constant low level pain and discomfort with it, and periods became excruciating. I got it switched back to a 5 year one and this cleared up. Again. the procedure was fairly quick as I knew my body and had good pain relief. My last one suited me fine up until around 2020, when the combination of the stress from the pandemic and using an expired lube gave me recurring yeast infections that lasted at least a year. I then discovered that it had slipped and so got it removed, deciding to switch to Fertility Awareness Method. After that, the recurring yeast infections stopped.

Personally, I would never get another coil again. The reason for 2 stars is I actually had the copper coil inserted in 2018 and it was okay but I had it removed in 2021 after asking for it to be removed for over a year. My periods were heavier as expected, but I also had thrush every month, BV multiple times and it just became so uncomfortable dealing with this constantly. I had the copper coil again this year (march 2025) and it was awful. The insertion this time took an hour compared to the 10 minutes last time. I was in so much pain I was heaving, I have had three babies and this was worse than birthing a child. They finally got it in and I ended up with a mild infection probably due to how long and how many attempts it took. A week later it started to settle down 🤞🏼 however almost three months later and I'm having it removed next week. I don't know if it's misplaced (they will be checking this first) but I feel it 'stabbing' me randomly every day. I will be walking and suddenly stop and feel like it's stabbing me or trying to come out, but I can still feel the strings. On two occasions it's hurts me during sex which is a red flag. My periods are 10-12 days long and I'm getting through a pack of pads every 1-2 days, plus the thrush is back again. I was offered a replacement however I have declined and I am currently trying to decide which combined pill may be best for me, tho I am nervous about going on the pill now!
