Family Planning Plus

Pregnancy is possible but unlikely.

The Depo Provera shot remains effective for up to 13 weeks. Practitioners generally schedule these shots 12 weeks apart. Therefore, you may have still been protected by Depo. If there were 13 weeks or less between your two shots, the Depo still would have been effective and the morning after pill would not have been necessary.

If more than 13 weeks passed between your last shot and the unprotected sex, then you were not protected by your shot and pregnancy is possible. In that case, the morning after pill would have helped to reduce your risk of pregnancy.  If this is the case, wait approximately five weeks and then take a pregnancy test.
