Clue Birth Control is a new FDA cleared fertility awareness method that uses an algorithm to provide personalised pregnancy risk predictions by calculating when you are fertile. It's different from Natural Cycles in that it doesn't rely on you recording your temperature to work out when you are fertile, it only uses menstrual cycle data. You need to avoid sex or use other protection like condoms on your fertile days. It's launching soon!
