Natural Cycles App vs Symptothermal method

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.

I had been on PoP contraceptive pill for nearly 10yrs, I have also tried CoC's and injection prior. I wanted to learn more about my body and be natural. This method takes a lot of research and understanding in order for it to work and be effective. I read books and watched YouTube videos to educate myself and joined FB/Reddit group. I use an app called read your body to input my temperature and other symptoms to track where I am in my cycle. It is all done manually by me and not relying on a system like natural cycles to do it for me as this is less reliable....Since stopping the pill my libido came back which is great and I feel emotions depending on where I am in my cycle. My Cycle regulated within 2 months after stopping the pill and for the past 3 years I have learned what is normal for me. My cycle is very text book 28 days long on the dot every month, I ovulate on day 15. This method works for me, I haven't gotten pregnant but on the days during my cycle I could get pregnant, we use condoms rather than abstaining. I would say it took me about 6 months to learn and feel confident in this approach.

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.

After bragging about the natural cycles for a while, and following it religiously, checked everyday, noted everything, I fell pregnant twice. I was someone who was super regular as well, so the app knew my cycle very well. I thought the first was an outlier then it happened again. Stress, exercise or changes in the normal routine can change your natural cycle, so the app can’t see what’s going on inside your body. So, this method is great if you’re not worried about falling accidentally pregnant and having a baby. If not, use contraception.

Literally no side effects, no fake hormones affecting my body or mental health. Use symptothermal - 11 months in and find temping and checking cervical mucus easy and not at all laborious. We use condoms during fertile window (for me that’s usually about 9 days) and unprotected the rest of the time. No scares and I feel confident and secure with this method. I’ll never go back to hormonal birth control!

I developed a rare side effect on hormonal birth control (hormone mediated vestibulodynia) which I am finally feeling is mostly treated after almost 11 months off HBC. My libido is back and I feel so in touch with my body. Never going back!

You need to know what you are doing with this method (get a good educator to teach you) but once you’ve got a hang of it, it is such an awesome way to manage your fertility.

I follow taking charge of your fertility rules, track using Kindara app. I love no hormonal side effects, found it easy to detect ovulation and I’m enjoying learning about how my body works. We use condoms when I’m fertile which is around a week per cycle which has been totally fine and much better than I expected (having been on the pill for years!)

A very empowering contraceptive method that allows women to learn about their own bodies and to work around what's natural to avoid pregnancy. Any symptoms that I have listed such as migraines occur during PMS. I would highly recommend the Sensiplan method as it has a typical failure rate of just 2%, and a perfect use of 99.6%.

There are several methods under the symptothermal umbrella term, and efficacy rates are based on learning with an instructor. I learnt with an instructor from fertility UK, this was very affordable for a lifetime of cycle knowledge and a year of chart support. The method involves me taking my temperature upon waking and observing my cervical fluid throughout the day, recording this information on a chart which I use to work out my fertile and infertile days. This method is easy to use once you have learnt. The number of infertile days is very dependant on the individual users cycle, but I typically get ten days where I can go unprotected once I have confirmed ovulation and also four days at the beginning of my cycle available to use. The rest of my cycle would be considered my potentially fertile/fertile days, where barrier methods (reducing the efficacy to that of the barrier) or abstinence/non penis in vagina sex would be necessary. A consideration is that the altered sexual behaviour would have to have the sexual partners cooperation too, as they would also have to be willing to use a condom or have alternative sex on the fertile days. I personally have found this method very empowering, having real-time data of what my body is doing and fertility status, working with my cycle phases instead of fighting against them. Learning about my body and reproductive health in ways that are not talked about in society and it is knowledge that should no be hidden from menstruators.
