Seriously heavy periods (wearing nightime pads and a tampon and still bleeding through my clothes in like an hour) and sometimes extruciating cramping. A lot of spotting between periods also which I've never experienced before. Nurse has told me that the coil should not affect my bleeding and I've gone straight from the mini pill to this so it may have been that the pill was improving my regular symptoms more than I realised.

I chose to have the copper IUD inserted in January 2023 because I'd had a bad experience previously with the mini pill (mood swings, decreased libido, and vaginal dryness) and I wanted to try a non-hormonal contraception. The process of getting it inserted was one of the most painful things I've ever experienced with severe pain, cramps, and dizziness. The doctor and nurse I had were wonderful and very reassuring, which made the process slightly easier. I would however, highly recommend anyone thinking of getting it to ask for pain relief if it's available. I'm certain it would have made the process much better and less traumatic for me. What followed was 6 months of intense cramping and spotting at random times of the month and extremely painful, heavy, and long (between 10-12 days) periods (I was lucky to have very light periods before going on any contraception which is one of the reasons I opted for the copper IUD). After 6 months or so my periods settled down to become shorter (5-6 days) and more regular but remained extremely heavy with lots of dark blood clots and severe cramping/back pain - to the point where I would have to take days off work and couldn't exercise normally because I felt sick/dizzy from the pain. The severe cramps started like clockwork on the 7th day before my period was due and continued until the end of my period meaning I was having up to two weeks a month of severe cramping. I also experienced cramps and thick, brownish discharge/spotting around ovulation. Other than the heavy, painful periods, I experienced none of the mood swings, weight gain, or loss of libido that I'd experienced on hormonal contraception, so the copper IUD was great for that. If anything, I experienced a notable increase in my libido! I chose to have the IUD removed about two weeks ago, after just over two years, because I was finding it increasingly difficult to cope with the intensely painful cramps and heavy bleeding and I developed severe iron deficiency anemia, likely due to my heavier periods. I was nervous about the removal process after finding the insertion process so difficult but it was significantly less painful and super quick. I had some light spotting afterward and some minor cramps but nothing too bad. I'm yet to have a period after removal and I'm, so far, two days late (confirmed not pregnant). I would normally have had at least a week of intensely painful cramps by now but so far, nothing. Overall, the copper IUD was great at the times of the month I wasn't bleeding or ovulating and I liked not having any of the side effects that come with hormonal birth control, but it ultimately wasn't worth the heavy and painful periods/iron deficiency anemia for me!

This post is for those considering the copper IUD. I know it is scary and you can find many horror stories online, so I thought I make the effort and share my IUD journey with you which has been very positive. Insertion: Got the IUD on the 4th February Insertion was uncomfortable and for a few seconds very painful but it did go away very quickly. I did bleed a little bit as well but I always do when they are examining my cervix. I’m very sensitive down there. Note:I have never given birth and my GP said that it can be more painful for those who never given birth vaginally. The GP who did the insertion was absolutely brilliant. She talked me through what she was doing and she prepared me for the most painful part. There was also a nurse present who was literally holding my hand through the whole procedure. It was such a positive experience. I’m grateful for both of them for making this experience so manageable. Right after insertion: I wasn’t in pain afterwards - I only had a mild sense of discomfort like you would have after a smear test. I even went for an hour walk right after the procedure, so it was really not bad at all. Please note that I’m a physically active person, so walking for an hour doesn’t tax me much. Others might have different experiences and it’s absolutely fine if you just go home and rest in bad for the rest of the day. That’s what i was told to do to be fair. Days After insertion: The cramping was moderately bad after the next 4-5 days, spotting was light After the 4-5 days cramping intensified especially after exercise and at some point the pain made it difficult to walk. Never felt cramping like that before. It made me very irritated as well. Normal painkillers didn’t work, I had to take cocodamol to get some relief but it was short term. Later it turned out that it coincided with my PMS. I was bleeding everyday after insertion, so it was hard to determine what was menstrual bleeding or bleeding because of the IUD insertion. Around day 11 cramping settled significantly. I only had occasional cramps which don’t require pain killers. I think I got my period on day 12 (16th Feb or 15th Feb) because the bleeding intensified around that time. It is the 17th February today. Moderate bleeding (more than usual but moderate) very light cramping. Fast forward March. After my period in February, I did not experience anymore unusual cramping - even after exercise. I got my period on the 9th of March. I did have some light cramping and mood changes as PMS but nothing unusual. The cramping was very moderate and did not require painkillers. Bleeding lasted 6 days with 3 days of heavier bleeding -3 pads a day- which for me is heavy bleeding. I have had sex a few times since insertion and my partner couldn’t feel the strings, so no problem there. Did not experience any dryness and my sex drive during ovulation is definitely higher than when I was on the pill. Overall very happy with my wee copper coil. 😊 Just a reminder that negative stories often get more attention than they deserve—people are more likely to vent about bad experiences than take the time to share positive ones Will keep you updated!

I’ve been using NC since 2021, I use to love this app and tell everybody about it until I had sex on a green day and got pregnant. I used to think it would never happen to me as I’ll use the app right. Measured every day and was very religious with the app. However, I ovulated earlier and fell pregnant! The app only goes off previous ovulation compared to current meaning it doesn’t prevent pregnancy as yes you have red days but it’s just a prediction! For example green day on day 6 (had sex) and ovulated on day 10 (red days) and fell pregnant. Ovulated 5 days early! Sperm can live inside you for 5 days hence why I’m pregnant and will be getting an abortion.

I've had an entirely positive experience using Natural Cycles. While using the impant I was struggling with acne, mood swings, irregular periods. And since swapping to use Natural Cycles I've felt much better in myself, my periods are very regular, I feel I understand my body and cycle so much more, and my skin has cleared up. In 5 years of using it it's been 100% effective at preventing pregnancy, I'm very careful to measure consistently, and I use the Oura Ring to help get accurate readings. But this small effort seems like a small price to pay in exchange for getting rid of all the nasty side effects of my previous contraception

I started using Natural Cycles a few years back. I was never on any birth control as a teenager as my mum didn't want my young body being put on hormones. However, once I settled down with my current long-term partner, I wanted to have the peace of mind that I wasn't going to fall pregnant. The first few years of using Natural Cycles were great and empowering, understanding the changes in my body and knowing when I had ovulated was great. What I had failed to understand was it predicted with its algorithm your date of next month's ovulation based on your previous month. Well. I managed to fall pregnant not once, but twice in the space of 8 months. The first time around, I thought it was my fault and I had not taken my temps properly (even though I never had an issue in the past). I had a surgical abortion as I was 3 months pregnant before I actually found out. I was willing to try again and really get to grips with it even though the clinic was very strongly advising me to go on some form of HBC. In the past 6 months, my body has recovered from the abortion and got back into its usual swing of periods and I saw I was ovulating again. This time around I invested in an Oura ring to pair with my NC app to be certain of my temps being taken. All was well, I stuck to my green and red days religiously. I use the pull-out method on red days (if we do have sex). And I trust our pull-out method completely because we definitely know he does not ejaculate inside of me or we tend to stick to oral sex rather than penetrative. I noticed my temperatures lately had been higher than usual and my ovulation was confirmed a bit earlier than usual. I didn't think much of it as I had stuck to our red days and green days as shown. When I went on calendar view, I saw that my fertile window just gone was a lot shorter than 6 days and I had unprotected sex (on a green day) that was 2 days before I ovulated. I did a test and indeed am pregnant yet again. I contacted NC straight away and got them to go through my data, which they did and have taken full responsibility for the muck up with their algorithm. I advise you to check your fertile windows and note any other observations (cervical mucus), because the algorithm cannot be trusted. And from what I now know, ovulation may change throughout different cycles (stress, sleep etc). I will no longer be using them ever again which is sad as I did so enjoy using it.

First few months lots of ‘red’ days (no unprotected sex days). Coming off the pill was a personal choice and brought back lots of issues i.e needing prescription pain medication. However, my sex drive and mental health have significantly improved and impacted on my relationship. I’ve used natural cycles for 2 years religiously and no problems or pregnancy.

I’ve been using the Natural Cycles app with the Oura Ring for about 6 months now, and it has been the best thing I’ve ever done! No side effects and I’ve never felt so informed about my body. I love that the app also informs my partner of when green/red days begin, so the contraceptive burden is on him too (in that he doesn’t have to ask me what type of day it is - we both know, which is nice). For peace of mind, I used the Oura ring for an initial period of three months to let the Natural Cycles app gather data on my basal temperature, whilst using condoms as a contraceptive. Then, when I felt confident that the app had a few months of data (and I was familiar with my own patterns/regular cycles), my partner and I reduced condom use to red days only. We have had zero pregnancy scares in 6 months, and using this as contraception has vastly improved our sex life. I’d honestly recommend it to anyone who is looking to escape hormonal contraceptives. The Oura Ring is expensive, but there’s no way I could remember to take my temperature every morning otherwise (and no way am I setting my alarm every morning… Sundays are for sleeping in!), so I’d recommend buying one if you do plan to use this as a long-term contraceptive and don’t want to be chained to the digital thermometer/same wake-up time every day.

I have used Natural Cycles for years now (alongside condoms when ovulating) and love using a non-hormonal method. I used to get side effects from the combined pill and mini pill so I have seen an improvement since coming off those. The data aspect of recording your temperature and seeing the patterns of my cycle is something I find really interesting. Plus the reminders of ovulation/upcoming period/breast checks are always helpful. I know myself and my body better since tracking my cycles.

The Natural Cycles algorithm does not work to accurately track ovulation and therefore prevent pregnancy. Evidence based FAM/symptothermal methods use a '2 check method' including temperature and cervical fluid patterns. Natural Cycles only tracks your body temperature. After using for a few months I noticed my safe/green days changed after the date. So I had (what I thought was) safe unprotected sex in the non-fertile window, but then by the end of that cycle those days had changed to red/not safe. Surprise surprise, I got pregnant and had to arrange a termination. Since stopping this I have started using fertility awareness methods successfully for 4+yrs. Natural Cycles is just too risky without a 2 check method, and basing it on an algorithm.

I loved using Natural Cycles as it let my body just be itself. It was very effective for four and a half years…until I unexpectedly got pregnant! I will fully admit though we would occasionally take risks on early red days, and we know where we went wrong the month I became pregnant (travelling with time and environment changes led to confusing temperature readings coupled with not using enough caution). The only downsides of NC for me were needing to be on a predictable routine for morning thermometer readings (may be challenging for those travelling a lot or on shift work) and we had to use condoms or abstain during ovulation - which is of course the peak time for when you want some action! Overall though I would recommend it and will probably resume using it once our sleep schedule normalises with our beloved new baby. Having been on the pill and using a copper iud for years, it’s just hard to beat having zero side effects and letting your body do its own thing.

Absolutely brilliant - after being on hormonal contraception this has been like a breath of fresh air. Natural cycles works so brilliant for me and I’ve never felt so in touch with my body and emotions. Genuinely lifechanging - if the you meet the criteria for this (regular periods, fairly routine lifestyle) then I could not recommend it more.
