Question: is it possible to get pregnant even after taking emergency pills?
Answer: While the morning-after pill delays ovulation, the IUD prevents a fertilised egg from implanting onto the lining of the uterus, and has a success rate of more than 99%. Two in every 100 women who use ellaOne will become pregnant, and an estimated 0.6-2.6% of women will become pregnant after using Levonelle.
