It may be hard to determine how many pregnancies the birth control pill is able to prevent. Mostly because there is no way to know for sure how many women would have become pregnant if they hadn’t taken the pill. But according to research carried out by the world health organization in 2010 only 37 out of 1696 women who used the morning after pill got pregnant after sex. This is an indication that the emergency pills work effectively.
