Which protective method should I choose?
How you choose to protect yourself on Red Days is a personal choice; however, Natural Cycles recommends using male condoms or abstaining from vaginal intercourse. We don’t recommend using withdrawal on Red Days – this is considered unprotected sex in the app.
To understand which method is best for you, it’s important to consider the effectiveness of each method. Since no method of birth control is 100% effective, if you are sexually active, there will always be a risk of pregnancy. However, some birth control options are more effective than others.
