Birth Control Pill

Aside from the standard 1 percent what is the chance of becoming pregnant if you miss a couple days of your birth control medication then have unprotected sex after 4 days of taking it as prescribed?

It is difficult to make a likelihood estimation based on the information provided. However, given that the menstrual cycle is regular then it is safe to assume that ovulation occured on day 14 of the cycle. That means, the highest probability of getting pregnant is on and around day 14. Not taking birth control pills increases the risk of pregnancy. The further away from day 14, on either side, the day the intercourse took place, the lesser chances of getting pregnant.
