I assume you've been having unprotected sex (as in without a condom or other barrier method)? If you were having unprotected sex before the shot then I would get a pregnancy test. I don't know anything about depo, but I figure that pregnancy tests would still be accurate.

Even if you'd just been having unprotected sex after getting the shot, I would still get a pregnancy test, but that's only because I don't know how effective depo is.
