If its a serum pregnancy test, and you have it drawn 12 hours or so after your shot....you should be fine. If its a urine pregnancy test (I doubt they would trust that for the purposes you mention)...it might be faintly positive if you take it within several hours of your shot. It's normal to have some hcg in your body, and our shot is low in comparison to the threshold of a serum pregnancy test. If in doubt, skip a day...be about 36 hours from your shot and get the level drawn....run home and take your shot. . Even if it shows up, they'll just repeat it if you ask....and skip longer for that one.
