A member asked:

I had a medical abortion 3 weeks before taking a plan b. i took it with 13 hours to spare, i haven't bled yet like other times, is there a chance?

A doctor has provided 1 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.
