Background check?

Hey! I passed the second interview and got called to come in the day after to sign my background check papers, which was yesterday. (A head from a different department helped me with my papers and said I should have gotten an email with the background check and acceptance form the day of the interview.) I signed a job offer acceptance paper and my background check, and was told it can take a few days to a couple of weeks. I have a clean record and have only lived in one place, how long should I wait before I call them to ask? I don’t want to miss out on anything and mess up 🫡
