My 3rd coil now. 1st lasted years. Second one fell out and I didn’t realise so accidentally got pregnant. 3rd has extra long strings so hopefully that won’t happen again. Never had much pain during insertion or removal or any added pain any other time just slightly heavier periods. Overall have always been happy with the copper coil just need to be better at checking the strings after each period. Feel happier and have a higher sex drive while it’s in.

I switched to the copper IUD after 8 years with implants and always irregular bleeding with the implant. The fitting was a little uncomfortable as expected but definitely bearable with a paracetamol taken beforehand. My first two proper periods were heavy-ish but not unmanageable (I don't remember having particularly heavy or painful periods before using implants); I felt some lower back ache and cramping for a couple of days at the beginning of each period but again this wasn't too bad, and it was nice to recognise a normal cycle after losing this when using the implant. Over the next four periods my bleeding has got a bit lighter than the first two, and I only feel occasional cramps or back ache so I'm very happy with the IUD and would definitely recommend it.

I've had copper coil since february 2024 and I feel so good that my body can have a normal cycle again after years on a pill. The insertion itself wasn't nearly as bad as people say. Yes it was a sharp cramp but it only lasted around 30 seconds and I could still talk through it so it wasn't anything traumatising. I took 800 mg of ibuprofen beforehand and that's what the doctor advised as well, it definitely helped. On the day I had it done I felt a bit weak and my lower abdomen felt as if I did a great deal of ab exercise. Nothing a couple painkillers and hot water bottle couldn't solve. My periods did become much heavier and more painful but before I had a coil they were very light and I had no pain at all so it is probably just about the same as most women experience every month. For this reason I wouldn't recommend it to people who already have heavy and painful periods but for someone like me it is manageable. I definitely feel so much better with it than a pill, sex became way more enjoyable and I'm more in tune with my body. I had the procedure done at sexual health clinic so I would recommend it over a GP. Overall very good experience and If I don't get any side effects from it over the next 5 years I will definitely do it again.

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.

I didn't really do this properly and only used it here and there! So I am definitely not an expert on this, but if you have regular periods and are organised I can see why this may be beneficial! Especially as no hormones

Started using Natural Cycles after having my first baby. I exclusively breastfeed and my first few periods after giving birth were all over the place. Tracking using the app just gave me a bit more info on my body and how long I was going between cycles etc. I’m just over a year post partum now and periods have returned to normal and I put knowing that down to the app. Baby still wakes a bit in the night so it can be a bit difficult to know exactly when to measure my temperature but the app has some helpful articles on this. Overall, love that it’s hormone free and that I can see helpful information on my cycle in an eat to use app! If considering, try finding a friend or someone with a referral code to get a discount on app subscription x
