In brief: Possible

Depo-provera is usually a pretty reliable method of birth control; however, no birth control option is 100% effective (except abstinence), so there is a possibility your girlfriend can get pregnant on any birth control method.
Depo-provera shots have to be given every 3 months; if your girlfriend is late in getting her next shot, the effectiveness of the depo is decreased.
