Best fertility awareness methods (fam)

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  

I used natural cycles to prevent and plan pregnancy- worked fabulously on both occasions. After my daughter was born I wanted a more solid contraception (sleep does impact your basal temp guys, so with a newborn, not the one)- now she sleeps through I will be going back!!

Natural Cycles App  

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.

Natural Cycles App  

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
