Clue Birth Control is a new kind of fertility awareness-based method (FABM) that is enhanced by app technology. Clue Birth Control is hormone free, side effect free, and FDA cleared. It’s based on an algorithm that uses your cycle data to predict which days you’re at a high or low risk for pregnancy. To see your risk predictions, you only need to enter your period start date each cycle. On high risk days, you must use a barrier method such as a condom every time you have sex that may result in pregnancy.
