Yes people do. Here are some stats
EllaOne is a morning after pill which works until up to 120 hours (5 days) after intercourse. Studies have shown that ellaOne is up to 95% effective when administered to women between 48 and 120 hours after unprotected sex.
Plan B -Levonelle is:
95% effective if taken within 12 hours of unprotected sex
85% effective if taken between 12- 24 hours of unprotected sex
75% effective if taken between 24- 48 hours of unprotected sex
58% effective if taken between 48- 72 hours of unprotected sex
After the first 12 hours, the effectiveness of Levonelle starts to decrease while ellaOne remains 95% effective until you pass the 120 hour mark.
To put it into context, when you have unprotected sex, your average risk of pregnancy is around 1 in 20. With Levonelle, this risk falls to around 1 in 40, but with ellaOne, it is just 1 in 50.
