Quite effective: Emergency contraception (EC) pills are used after sex to lower the chance of pregnancy by about 70-80%. EC is a high dose of birth control.

Question 4

how effective is plan b if took on day 3?

Accepted Answer

Plan B: is most effective when taken within the first 24 hours of intercourse and loses some effectiveness the further out it is taken. It is still effective 72 hours from intercourse.

Question 5

how effective is plan b if taken 3 hrs before sex?

Accepted Answer

Probably effective: Plan B is 95% effective if taken within 24 hours after intercourse.  Its intended for use in an emergency so there is not a lot of research on what happens if you take it prior to intercourse.   However, it works by delaying ovulation and it makes sense that it would be equally effective if take just prior to intercourse or just after.  But this is my opinion and not based on research.
