Did not work, I got pregnant
Bought the Oura ring and yearly subscription to prevent pregnancy. Also bought ovulation test strips to test for ovulation when the app prompted. Did this for four months after getting my first postpartum period and while breastfeeding (started at 11 months postpartum. It was very accurate at predicting my period however was not good at tracking my ovulation despite consistent testing and wearing my ring 24/7. I experienced an unplanned pregnancy and when I looked at the day the app said I ovulated, my recorded temp was the lowest it had been all week. I’m not sure if breastfeeding played a role in it but I would not recommend this method to prevent pregnancy as the ovulation tracking was ineffective for me.

I’ve been using natural cycles ever…
I’ve been using natural cycles ever since getting off of birth control years ago and switching to NFP. This app taught me more about my body and cycle, helped me conceive our first baby, and simplifies natural family planning so much. And now the natural cycles band makes measuring and tracking effortless so it’s easy to know when I’m fertile based on my temperature. I’m so thankful for this app, and I recommend it to every woman I know.

It has made me much more aware.
It has made me much more aware of my own body and cycle. I understand more about different phases of my cycle and what they mean for me, and also how to recognise them myself. I like the facts they share, and the reminders for breast checks and similar things.
My only issue is, if you're someone that the pill doesn't work for because you just can't remember to do something at the same time every day or you do for a few months then taper off? It's not for you. You've got to do it every day to keep the information consistent and keep the red/green days consistent. I did great for maybe 4 to 5 months, then started struggling with every day 🤦♀️
I have really enjoyed using natural cycles. I started using NC about 3 years ago after deciding to come off my contraceptive pill. I now have a better understanding of my body and how my body, emotions and mind changes over different cycle phases. I have had no pregnancy scares (touch wood) and I love being able to track my own cycle. I also like how they have different modes for conception, pregnancy, postpartum and peri menopause.
My only complaint is the price. This year they have increased the price of their yearly subscription and it is on the more expensive side. It may not be accessible for everyone.
I love this app! Makes periods and ovulation predicting so much easier. I feel more confident in not being on birth control. I’ve been sexually active for 2 years with my partner this makes me feel less anxious if my period is ever late.
At first I used the regular thermometer, which worked just fine but I’d often forget.
For convenience and additional data tracking I bought the Oura ring and LOVE it. Not only does it automatically take my temp everyday for me but I can more easily notice when I’m stressed and not being active enough. It’s been super helpful.
