When getting the Depo-Provera injection, you need to return in 11-13 weeks for you next shot. We usually tell the person to come in at 11 weeks so they have a 2-week buffer in case anything comes up. If its over 13 weeks since you had your injection you would need to use another method like condoms until you were able to make it in.
You can also call the options for sexual health sex sense line on 1-800-739-7367. They specialise in birth control and could speak to you about your specific situation e.g. what date was your last shot.
