20% pregnancy per yr: Best way to estimate is to ask what is chance of getting pregnant if you keep using withdrawal method over the course of one year. This risk, based on research, is about 20%. Given that you may not have performed the withdrawal method properly, the other number to reference is the chances of pregnancy when no method is used. That number is about 85% per yr. Divide by 13 to get risk per month.
