When to expect period

I just finished my pack of birth control pills, had my period, but made the decision not to go back on the pill. Will I get another period this week? I can't remember what happened when I went off before lol. I know everyone is different. My periods have always been easy to track when I wasn't on the pill, so I can't remember if I will get another period in 3 weeks or if my body will have to reset from being on the pill. If you went off the pill what was your experience?
