The Natural Cycles app is a mobile application classified in the EU and by the FDA as a medical device for contraception. Technically it is a fertility awareness method. The app contains an algorithm that analyses your temperature (measured using a thermometer) and menstrual cycle data to calculate when you are fertile, and tells you to avoid sex or use other protection like condoms on your fertile days. Unlike other fertility awareness methods it tries to minimise human error as the algorithm does the calculations and interpretations for you.

Natural Cycles App

How does the Natural Cycles App work?

The Natural Cycles app is a mobile application classified in the EU and FDA-cleared as a medical device for contraception. It's a new form of 'digital contraception' that stems from the symptothermal method. You record your temperature daily and log it into the app using either a basal thermometer (that you can get from Natural Cycles),or insights from an Oura Ring smart ring which records health insights like your temperature heart rate and sleep quality.

Natural Cycles App  

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.

Natural Cycles App  

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.

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

Natural Cycles App  

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

Natural Cycles App  

I LOVED this app, it was truly the best option as someone with a medical condition hormonal contraception was not possible and the side effects of others seemed too problematic. However after 13 months of bragging about how great my experience has been with the app I fell pregnant. This was devastating as I followed the app religiously and was an outcome I did not want. I even think I know what green days caused this as around my 10month in it began to green light the day after my period had ended, which was new. Having trusted the app so far I began having unprotected sex on these green days after my period not long before the pregnancy. Since this has happened I have research further and I believe this app is not being investigate enough and it’s far less efficient than we are led to believe. Despite of this I am still using the app however ,we now use condoms even for most of the green days as I feel I cannot trust it. I am seeking alternatives but with my medical background it is slim pickings. My take away- there are no side effects accept the very real possibility of getting pregnant. If you see any ad on Instagram rn it is swamped with comments with women having got pregnant from the app and I suspect those of us who had to have an abortion have kept quiet. I wanted this to be a true alternative to all the havoc other forms of contraception cause but have been let down in the worst way.

Natural Cycles App  

I am so pleased to find this after years of side effects from other contraceptives. Doing this method takes work- ovulation testing and I use an oura ring to accurately measure temperature. I wouldn’t recommend this for someone who doesn’t understand how it works, doesn’t understand their body or does not have restraint to use barrier contraception or abstain during red periods. It really works for me and I’ll be using it for the foreseeable.
