Yes, possible: One injection of Depo-Provera lasts for 3 months, regardless of how long you have been receiving injections. If you had unprotected intercourse after the expired date of your last injection, there is always the chance you could become pregnant.

Possibly: Oobtain a home pregnancy test. They turn positive within 72 hours before your expected period. If it's negative, repeat in 1 week.
